Hitchcocks Forum

Does anyone know a good mechanic in the Yorkshire area who can rebuid my bullet 500 crank? Finally got the cases apart yesterday without any tears or smashed alloy. Used wedges of wood to tap in between them and they slowly separated. After lots of good advice on this forum I still can't decide wether to stick to the floating bush/alloy rod or go steel/roller, or maybe steel/bush.

Hi CHRIS -------------- I'm in a similar situation re}--- "Which way to swing ??" ----------- hang on, no that's NOT what I meant at all !! LoL !! Referring to the choice of rod/bottom end, I'm in a similar situation with my No.1 Bullet. Reading other forums and contributors I think the answer lies in the TYPE of work you intend the bike to do weighed against your fiscal limits ???--------Racing OR regular fast, motorway or similar, then the "full monty" ( ie steel rod with rollers, high-flow oil pumps, etc.) is called for-- especially in terms of reliability. In this case you can forget about any money restraints, I would say. Normal "club" use with the odd spirited visit to 70 mph ??, OK then a steel rod with floating bush will suffice. Bog-Standard build with commuting/touring in mind ??---then the original alloy rod /floating bush combo. will suffice.... I'm opting for the steel rod/floating bush scenario with a Hitchcocks forged piston on top. I've been running that piston for the last 3,250 miles and it seems ok to me.( also had a de-compression plate in to give an approx 7:1 CR but will revert back to standard 8:1 for next year)....an Amal 30mm Mk1 Concentric breathing through a paper air filter with a semi-restrictive exhaust completes the set-up.

chris ,whats wrong with the rod thats on the crank is it u/s? or are you just being paranoid?i would say build the motor to do 50 mph i can,t ever say i,ve seen you go any faster!!! only joking ,fetch your assembly to the meeting on thursday ,i,ll give you a tip maybe we have a top engineer in the club ,score him a smoke and ken could be your man?????????????

Thanks Alan, I think I'll be doing all of those scenarios so will really need the 'full monty' Guess I'll have to take my time and buy each bit before the re build, fiscal limits being an issue. I have a monobloc with bellmouth/open pipe and (contrary to what Grunda says)like to use the engine. Paul, never thought of Ken.

Chris it could be worth a phonecall to>>>> http://www.mollsprings.co.uk/
