How has been the performance , any heating issues.

Also members- there are a lot of US based companies who sell sleeves, is it possible to order a sleeve with pre cut ports? Asking this as I am eying a Shogun and cylinders are next to impossible to source.

Just bumping up this thread, The Great, as there were no updates.

Can you share your experience, as the job should have been completed and must have ridden the bike also after that?

The performance is great, highly suited to my style of riding (occasional bursts of rush riding, mostly smooth and silky riding to enjoy the grunt of a 2 stroke, and knowing that I can put most of the production 4 strokes to shame anytime.)

The compression is great and till date I haven't experienced overheating issues. In fact the average has significantly improved too although that wasn't on the list. But to be honest haven't ridden the bike out of the city so cannot be sure of long rides. Max 50 kms in the city per day.

Regarding foreign sleeves I am not sure because I haven't tried it, here in Mumbai we have specialist Rx guy who knows how to prep a 100 or 135 4s and 5s. A specialist of Rx and Bullets you can say. Hence had the trust in his work. Honing, sleeve job, port matching, chamfering, port polishing etc... nothing had to be told he did it all by himself.

As far as shogun goes, be sure that you have the confidence of sourcing original parts, do not get into it just because the bikes can be obtained very cheap in second hand market. Believe me a shogun is much harder to rebuild than an RD . Because of the US market the availability of RD parts are easier to source than a shogun which was mostly produced in asian countries. And a simple item like a manifold can cost you a fortune (almost 20 times the original cost) because of scarcity and rareness of parts.

Yes, the bike is running great and there is a significant change in the feel of the engine after 3k kms. Proper run in with lots of care taken surely does make a difference. Every 1000 kms the bike surprises me with the increase in performance. Totally the bike has done about 5k kms till date.

In my opinion a perfect sleeve job is only 25% of the battle won. A deeper understanding of the bike, its true potential, its limitations all have to be studied in order to achieve good results. Other than that reed valve, carb setting, carb jetting , air filter, oil brand and viscosity, electronics, crank shaft, cat con health, Cdi, etc etc.... all have to be studied as per bike to bike and then adjusted accordingly. PS - Original stuff does make a difference overall.

Hooligan performance minded people would not like it as the original company blocks do have an edge over sleeved ones. Also most of the sleeve jobs done are not properly carried out and hence the bad reputation. It does require a specialist.

All in all "I am very happy" and that's what matters the most.

Nice to note that a job well done and the owner enjoyed the job as well as the results. Here is to many more miles of pleasurable riding!


Yes, original parts do make a difference, as the tolerances are finely calibrated.


What was the make of the pistons and piston rings you used? And also the oil (engine as well as 2T)? Did you make any changes in the oil pump, as well as the carb jets for the run in after the re-sleeving?
