Hello Titus, Thanks for your input. What would you recommend for a Front tire size? I know I said 15" but maybe I should have said 17".
Or I might just stick with the 19" for now.

Hello Jeepster, Wow that is some Springer pic you got there. Looks retro.

I ordered mine from an ebay dealer "American Classic Motors". They have quite a reputation score (over 150K of sales through ebay), but also you can find alot of negative feedback on them. Most of them are from customers who could not fiind a perfect fit for the make they actually have, so we cannot hold the dealer entirely responsible for them.
Anyways, they have been really helpful with me and to help find the perfect parts and a really reasonable quote.

Attached are the pictures of the parts + a rough price quote. Shipping them took around $230 through FedEx, but it was worth it. Package weight was around 25Kgs. Delivery just took 5-7 work days! Thats lightning fast as compared to anything that comes through USPS and India Speed Post (20-30Days due to custom clearance).

PS: The springer I ordered is 2" over stock, thats around 25" of length from the bottom neck hole to the center of the axle hole. Stock enfield Fork is around 22" length I think. So I will have to rake the neck of my Mach a bit to adjust the length.

Started working on the bike. I am getting help from a local assembler too.
Also discovered that the Neck Stem from the springer is shorter than it needs to be for the RE Chasis. I will have to get another one manufactured at the lathe shop, and hopefully they should have it ready in a day or two. Hopefully things will be smoother after I get that done.

Planning to dump the stock Ammeter and Speedometer. I will be getting a Digital Speedometer next week which will go on the handlebar, and it is compact so the bar will still look neat, clean and elegant. The ignition switch will be relocated to the right side, after the air filter.
I would also be lifting the petrol tank by a couple of inches, so that some of the cable can be dumped under there. Excited, but sadly not moving as fast as I hoped it would.

Nice sketch Jeepster. Start working on it . I need to create a sketch someday too to see where I am headed.
Right now, its more of a mix and match frankenstien bike. Ha!

Got the neck stem back from the lathe. They decided to just trim the top lock nut by half its length to get us the length it needed. I will update you guys on more of the details and progress later today.

Hey Joe , There was a nicely executed Bobber Bullet which was show cased at the Thrissur auto show Yantra 2010 , I will try to pull out some snaps and post it here. But it was a very simply and economically executed mod job.

I too have modified my royal enfield thunderbird and want a similar single seat setup for it, but the rear seat chassis bar is an issue, if i cut it down will it not effect the chassis support structure..

Good looking TB. You can easily fit a single seat setup easily on your TB. It will not hinder the stability at all. You may have to get different kind of mud guard stays though.

I googled for it and i think i found one called "My Maiden". Not sure if that's the one you were referring to.

Today Trivandrum was brought to a stand still because of the death of Chief minister Karunakaran aged 92. So the guys who were willing to help assemble could not work because they were told not to work today.

Oh well, hopefully more assembling to happen tomorrow!

Default WIP - Noob guide to fitting DNA Springer front end on Bullet

Good progress today and we made a few discoveries along the way. Fitting the springer onto the stock neck went smooth for the most part. Here is a list of the changes and alterations done during install and those left to do.

- As mentioned earlier, the lock nut of the springer was reduced by 2/3rd of an inch so that it would fit on the stock neck of an RE. We figured that it would have to be further reduced by another 1/2inch so that the handle bar risers can fit in it's slot properly on top of the springer base.

- Ball bearings and cone nuts - stock parts from my Machismo was used.

- Front axle kit that came along with the Springer is a bit thick than that would go on the stock 19" wheel and bearings, so either this will have to be lathed and made thinner, or a Rear wheel axle with some alterations will have to do. We did a temp fit with an old rear axle, but it is a little too short for what we need.

The length of the springer is around 2" over stock bringing it to a total of 25 inches as compared to the stock fork tube length of 22-23" on a Machismo. Thats an additional 2-3" added to the front ground clearance, which I am not comfortable with. We will have to increase the length of the front chasis tube and also rake the neck to a minimum to compensate for the additional length.

WIP pics attached.


Other things left on the project -
Elevating the tank.
Fitting the forward foot controls.
Increase the rear swing arm length by 6-10" and width to fit a wider wheel 15" 150/80.
Wider front tire. Size undecided.
Relocating the battery and left side box switches under the bike.
Custom exhaust - single or double long straight tube.
Paint and polish.
Custom fenders.

Merry Christmas everybody.

dont bother with the sketches, the only thing matter is bike & you have got one .

EDIT: what are you planning about the tool boxes.

also i dont think that the rake angle needs to be modified.

Thanks Jeepster. The toolboxes will be replaced with some custom curved covers that would hide the battery and some electrical stuff behind it.

Yep, definitely going for a bigger profile tire, just haven't decided if I have to keep the 19" front or maybe go for a 17" front wheel. I am leaning a bit towards 17".
