| Prajeep and SS- please take a note of this- it's a humble request and can be checked up with the pros.  SS and Prajeep, you'll need to refit the front M45 tyres in the direction opposite to the arrow. I had mentioned this to SS elsewhere but he missed it i think. Coz imho, for fitting the M45 at the front, you have to fit it in the direction opposite to the tiny directional arrow on the tread. You follow the arrow on the M45 only for the rear. Front fits the other way round.  Note: You follow the arrow on uni-directional tyres when you fit- A tyre meant for the rear at the rear. A tyre meant for the front at the front. A tyre meant for the rear, fitted at the front, is fitted in the direction opposite to the arrow, i.e. opposite to the direction of rotation. If i remember correctly, this rule was followed even while fitting MRF Zappers when we didnt have dedicated Zappers for the front. So when viewing a MRF Zapper from back, the grooves on the rear looked like '/ \' - for proper functioning. When the same tyre is fitted at the front, viewed from the front, the grooves on the front should look like '/ \', means they look '\ /' from the back of the front tyre. |

You may not like the looks but, if the fit is ok, the build quality is ok, then any danger? I used the oem black powder coated ones that came with my bike for sometime (heavier and better finished than the chromed option) and later shifted to the much smaller RXZ oem ones. They were very good in built as well as fit- the best i managed to find in Mumbai. Looked like a mini version of the original RX100 ones but also had room for the RXZ engine cowl. Best thing, they didnt come down as low as the big 'D' ones, which can get a bit too close to other vehicles in tight traffic or while over-optimistic leaning, but when bike was laid on its side, it didn't compromise on clearance. Did not utilise individual clamps as in the regular RX100/135 ones, that scratch the downtubes, and loosen or crack later but a bridge spanning both tubes. No loosening or rattling even after a long time and even the paint on the downtubes didn't get scratched. They were later stolen while my bike was being worked upon. :( Quote:
Ain't that Motul Ester a fully- synthetic oil. Then that is the last thing to use while running-in iirc. :( It will hamper proper mating/running-in of the engine parts. Ideally, one should be running-in the engine on regular grade/conventional engine oil and later shift to semi-synthetic or full synthetic as per needs/budget. If one can afford it, full-synthetic is a no-brainer. But it also doesn't make sense for a commuter kinda person. And during running-in, a lil extra output from the oil pump is kept to be a lil safe. But 2T pump at full- that will be fouling the plug, wasting efficiency and also compromising the proper mating of the parts and may cause glazing, what we want to avoid at all costs. Unless your 2T pump at full is pumping in what's the normal. Ya- different batches of RX oil-pumps pump slightly different amounts at the same setting. With age and wear and tear, o/p of some drops drastically and some eventually fail altogether. So it has to be set at the standard setting by monitoring the o/p. Quote:
But i made sure the pump is fine before starting on a long trip, 20-30 ml in 10L as bonus and another 50ml in a bottle for emergencies. Metering dosage of 2Toil is not simple and depends on estimated mileage too- which depends on several variables. Premix at petrol pumps is a approximation assuming estimated mileage at normal running and not excatly for our bikes. Ride hard and improper premix can cause damaged/partial seizure. Make sure you use good pipes- mechanics sometimes cut tatterred ends of old ones and refit- pipe is stretched and may get flattened or develop kinks, so pump works but still less oil to engine means a adamaged engine or partial seizure. Pipes of bad quality also suffer similar problems of flattening or kinking. Also during setting the oil pump, the oil-pump and the oil line have to be bled and then fitted to the carb after assuring no air is trapped- as Prajeep sir already mentioned. Quote:
Else it sounds ridiculous. You either use oil-pump, minor addition to tank is ok. Or you disconnect oil-pump totally from the engine and use your own pre-calculated premix. That one has to work out- how many ml of 2T to add to how many litres of petrol- based upon crusing speeds, the estimated mileage and the 1000ml 2T for 1000Kms average usage as a guide. Using premix on a standard bike with standard jetting and one can notice a mild drop in instantaneous acceleration as the premix is not as light as pure petrol. Plus any dirt in fuel, with oil, can be a bigger problem at choking jets than it is when oil-pump is used and oil is pumped directly into the o/p tract of the carb. Oil pumps usually fail as the tiny gear in the oil-pump is unable to keep up with a long sustained high revving engine, maybe due to not so good quality or improper fit. Yes, i have seen bad fits due to unskilled mechanic kill a good oil pump. Rally bikes do away with the oil-pump altogether as it's a huge risk on the reliability part given their sustained run for long periods at high rpms. They are known to run heavily ported engines with bigger jets and use precisely metered amounts of 2T premixed into the fuel based upon the distance to be covered. | |||||

| BHPian | Ok, now you got me all confused.  Please see the pictures below for reference. There are two tyre direction arrows in a tyre. As per my understanding, in the case of the front tyre, the tyre needs to move in the direction of the arrow saying <front> when moving forward, and in the direction of the arrow saying <rear> when moving backwards. So as in the picture, when my bike moves forward, the tyre rotates in the direction of the arrow saying front. Please correct me if I am wrong here. |

Saw both the pics of "both" the tyres and realised they just made it worse for users if i interpreted them right. :( Or maybe better for n00bs now, coz of some related issues earlier. Pics of the rear tyre helped me as you clicked then wrt to the rear shock. When unfitted, do the front and rear tyres bear identical marks wrt that front and rear 'lettering' with arrows? What size you running at the front and rear? Will you please provide full pics of each of the whole tyre in view as they are mounted from the exhaust side of the bike.- please. Just one pic per tyre is enough so that i can see the entire tyre and both the markings simultaneously. I need to recheck before i open my mouth and try to shove in my foot once more. Also, is the speed rating/max speed mentioned on them on any side. Any mention/print/mark where these tyres are made? These M45 look funny for several reasons along with those front and rear markings- "funny funny shoes".  Last edited by BIKeINSTEIN : 14th July 2008 at 13:36. | |

| ^SS- my net is dicey- waiting for the pics. Though if i have interpreted the above pics right, then the 2 tyres should be identical in pattern and markings except for the size. Coz Michelin M45 was a unidirectional tyre for rear and mostly still is. Earlier it used to have a few tiny arrows on the outer area of the tread. And all arrows pointed in the same direction denoting the intended direction of rotation. So one fitted the rear (usually a 3.00x18) as per the arrow- i.e. rear tyre rotates in the direction ofthe arrow. The M45 for the front (usually a 2.75x18) was fitted opposite to the arrow. The problem with those M45s was that many never saw the arrow and assumed it to be bi-directional and fitted it anyway they wanted. Others used to look at the 'L' shaped designer lines or whatever on the sidewall and assumed it to be an arrow- problem being it pointed the other way round on the other side. Also, since those tiny arrows were on the tread, they got scrubbed off after some running, especially after some corner-carving, donuts or stuff. So unless the rider/mechanic instructed the tyre-fitter or the latter was aware of it from previous fitment based on the tread pattern, there wasn't a way to find the direction on a used tyre. So maybe that's why they have two arrows on the same side of the sidewall now- one marking rear and one showing front. Wasn't one enough- just indicating the way it should roll when fitted at the rear? I hope and am quite positive it is that way. The new two-arrow marking can also mean/suggest- that if fitted at the rear, it should roll in the direction of the arrow 'marked' rear and if fitted at the front, it should roll in the direction of the arrow marked 'front'. Means we all were using it the other way round all this while.  But since i have seen the older tyres with single arrow that had no room for confusion, your present fitment at the rear is fine. That's why i said they made it worse now if they have those two arrows on the same side of the tyre and the need for full pics of both.  Last edited by BIKeINSTEIN : 15th July 2008 at 17:57. |
