i got my jets and shims in the mail today and i just had to go ahead and try it on my own. heres what happened, i switched from a stock #126 main jet and jumped up to a #130 main jet. i noticed the stock jet was a hex, but the one i replaced it with had a slot. i took out the needle and put in two .020 shims. when i measured the shims thickness i put two together and they measured .046 with my micrometer. handy being a machinist i can have access to tons of measuring equipment. according to google earth my average riding elevation is between 297-525 feet. all together the job was fairly easy and i got all worked up over it for nothing. thanks to everyone who helped me along the way. spark plug had a very light grey color with barely a hint of very lite tan before carb work. ill watch it. i also added a DG O-Series slip on exhaust, no noticeable popping in decel after a hard roll on the throttle. the TW seemed to like the change right from the start. after a few cranks the carb filled with gas and fired right up on half choke. choke off 10 secs later and good idle. thats right i said good idle.
started down the road and the TW shifted through the gears much smoother and it felt the the power had been more evenly distrubuted through out the gears, and i did notice more power in the mid and upper gears. the bike seems to run a whole lot better! motor seems to sound alot smoother as well. what should i try next?
i was surprised to see that the replacement jet was round with a slot, not hex. jetsrus.com claimed they where oem replacement for the tk carb. but it seems to be ok with the jet i got. if i have any issues at all ill yank it out and try what really is genuine yamaha. what would be gained if i went from a #35 pilot jet to a #38? it seems well now so im just wondering if its one of those, dont fix it if it aint broke, kinda things. hey rodney, second gear wheelies will be coming up next year. gotta completley break in the motor before wheelies can happen. but i know it will do it. ive never been on a bike with a clutch that i could not bring up.
I have an 1987 TW, It has the original battery.
It drains every year, I stick the trickle charger on it in spring
The neutral safety green lamp comes on.
It kick starts every time, and will kick start all summer long as long as I run it every day or two.
It never has enough juice to crank with...

Folks
Does anyone know what the current draw is for the start motor? I'm doing a total rewire and have put in place a motogadget m-unit, which has a 30A starter relay on built in. The destructions say that if your starter draws over 30A then use a seperate relay.
I've done a couple of quick...
I currently have my fork fluid-level at 130mm.
I'd like to increase it to 125mm, but I'd like to be able to do this WITHOUT dismantling the forks....so how much oil (in cc's) would I need to add to each fork to get there?
Or, more accurately....what does each cc of oil put into the fork, relate...
I'm looking to get a bit more top end from the old girl...so that she isn't as buzzy at higher speeds.
At first I thought about going 14/47...that's only 3 teeth on the rear and shouldn't make that much difference. I remember trying 14/42 with my old '01 but it was awful; add a passenger and it...
