Hi all
I am extremely desperate at the moment, I know it isn't VMX and I will take down the post if required.
A few months back I bought two TT600R's (98/99) with the intention to make one good bike out of the two.
One was bought from action as a stat write off, it was stolen and recovered. Missing the rims, CDI and the wiring was in a mess. Suspension and motor were mint though.
The other was bought cheap off Gumtree from the Gold Coast, it was meant to be sold as a runner, however, the owner couldn't start it in front of me.
Didn't worry me, I got it cheaper as I was mainly after the frame. Took it home, started the first kick for some strange reason. Motor was smokey, rattly, broken mounts, just a flogged out bike.
The bike had an intermittent spark, it would either start first kick, or not at all. So my father and I cleaned and checked every single connection on the bike, and tested every component we could. It appeared that the CDI was buggered, so I bought a CDI from a place in Belgium since Yamaha wanted over $1200 for a replacement(HPI ignitions) This appeared to cure the no spark problem, the bike would start, however it would give a major kickback. Overall we were happy with the aftermarket CDI, so we decided to try to get Auction bike running.
Swapped the rims, and the carbs (Carbs in the Auction bike were full of gunk). Chucked in the CDI, and there was no spark, the wiring harness was pulled to bits from whoever stole the bike, so we swapped the wiring harness. There was still no spark, after a bunch of stuffing around, it finally got spark again. However, it was almost impossible to start due to the kick back.
( Getting just over TDC and jumping the bloody thing).
When the bike was started, it ran really well, pulled through all the gears, lifting the front with ease.
Started to swap coils/stators/pickup/ everything, and no difference was made to the bike. After a few weeks of messing around, we eventually lost spark again. After a few weeks of not getting anywhere, we went to a local bike mechanic, explained our situation and he suggested a really well known Auto-Electrician workshop. They took the bike in, after a few days I got a call back saying they fixed it and were starting it daily, saying it must of had connection somewhere. Took the bike home, and it would not start at all. Rang them up the next day and they told us to take it back in. Supposedly the spark plug had fouled on it.
After this the bike started/rode amazingly for a few weeks, Started first kick every kick, and I rode it for a few hours everyday around the yard
(I was on University break)However, after a few weeks had passed, it was back to the kick back issue. Impossible to start by kicking, we tried clutch starting the bike. This was next to impossible due to the compression it has.
Today resorted to tow starting it. Pic bellow to explain the set up. Pipe over the axle
Took it around the back yard, would just lock up in every gear and tear the grass up, turned over a few times, but not enough to justify the damage to the yard. Took it on the driveway and it would just lock up going down the dirt driveway, so we took it onto the road
(Private bitumen road) , after some serious backfires/kickback sounds it started. Ran really well, let it run for a while to warm up. We then decided to use to original CDI again. We got the bike started going down the driveway, and it didn't appear to backfire/kickback as much.
So we then tried to get a timing light on it, and the timing light we have, we couldn't get to work. Not 100% sure why either. Turned the bike off, and started it twice first kick! Tried for a third and got major kickback. Swapped the aftermarket CDI and just got instant kickback. Swapped the CDI's back and forward for a while and we are just getting kickback.
Sorry for the long post, I am really desperate for help at the moment.
Any help would be greatly appreciated.
