I posted a few weeks ago that I was about to start a new full suspension build, well the parts have arrived.
Thought I should give a bit of background, I bought a secondhand commuter bike with a happy time motor. I have since decided to embark on a new project with a full suspension bike. This is my first full build, I have previously reinstalled just about everything on my old bike which has given me some experience.
Having had the odd share of to be expected problems with old bike I have taken the time to research and go with what has been tried and tested. This is a complete build of bike and motored bike from the ground up, I have just about finished it but mamaged to get some time spare so I thought I would start my build thread.
Frame: Salsa Caballero Full Suspension '03 - Ebay purchase
Forks: Marzocchi Dirt Jumper 1 - Chain Reaction Cycles
Rear Suspension: Manitou RL - CRC
Wheels: Double walled rims with disc brake hubs, 20mm front axle - CRC
Brakes: Hayes HFX-9 Disc brakes front and rear w\ 6" Rotors - CRC
Bottom Bracket: SBP 131.5mm Cartridge Complete
Throttle & Gears: SBP 8 spd SRAM Twist Shift
Cassette: SBP Megarange 11-34 Shimano 8 Speed
Engine: Rock Solid Engines
I have decided to create a REALLY tough and light mountain bike that is adaptable to a happy time motor with a SBP shift kit. This will be a daily commuter doing around 25km's and I needed something that will be comfortable and last.
I got the local bike store to prep the frame and put together the bottom bracket, rear cassette and headset. The first pic is of the bare frame, the second pic is the bike just about built. I have since finished the bike build and took it for a quick ride before I started the motor\shift kit installation. Rides like a dream, hardly feel any bumps, went up a few curbs and the bike absorbed it beatifully.
I must admit I was quite undecided at times on wether to put the motor on such a nice bike. But I did specifically buy the frame to suit a happy time motor. I started with the shift kit first and it all went together great, I had to file down one of the casted rear clutch case supports to fit the plate to the back of the clutch, apart from that everything was as per instructions.
I took Fabian's advice and have got some 1mm Stainless Steel and modified the engine mounts to spread the load of the clamps. I also had to modify the throttle to use the twist shift cable. I took the cable adjuster off the carby and have used that with the twist shift adjuster. The engine wouldnt fit in the frame with the carby cable adjuster screwed in, the cable end cap is now threaded straight into the top by persuasion. I used the original throttle sheath with the twist shift cable then woulnd wire and soldered the carby end of the cable.
The handle bars have the gears, front brake and clutch on the left with the throttle and rear brake on the right. That is about where i am up to at the moment have got the engine, cdi, fuel tank fitted too.
I just need to fit the chain tensioner for the shift kit, NGK spark plug cap and shorten the clutch cable. Then I can give it a quick double check and take it for a run. I will take some more pics and post them to show the build in detail. First priority though will be to finish it, hopefully will be able to take it for a test run tomorrow.
