Well, plucked away at it some more these past weekends. Garage it's at is about 45 mins away so I get about 5 hours a weekend to work on it. Talked to Santo on Friday, he'll be tearing into the shocks this next week. As far as assembly, swingarm and axle are on. Motor is all bolted in and wired up. Had 05 450r spindles in the barn so those got out on the front end. New flexx bars and on and cables are ran for the most part. Going to pull the stem out to polish it and make a spacer so flexx bars don't smash the tank. Rebuilt rear master cylinder and put a 450r master on the front. Need to find a set of 450r aftermarket pegs. May have a set of raths to go on but we'll see. May aim for unadilla as a debut race but we will see how far we get.

Tried installing a trx90 throttle on the stock carb. Doesn't seem to have enough throw to open slide fully. Anyone had this issue or successfully put a 90 throttle on? May end up just putting stock throttle back on but trying to preserve the shiny Nacs cover.

Forgot to take lots of pics but nothing to exciting going on yet. Just lots of polishing left to do on this old thing.

It all depends on what carb your running. I've had to take a pencil grinder to the throttle housing to get more pull out of them. You'll just have to mess with it. My 250r is still at my dads or I'd pull the cover off and snap you some pics.

Don't tell anyone but I even run trx90 housing on my suzukis before the 09's came out... Lol

Running a stock carb for now. I looked to see if I could grind the stop away in the housing but it's only going to get me like 1/8" of throw before it hits the housing.

The first half of the throw has almost 0 tension on it. Feels like it's just free play but slide is moving during it. Going to try the original throttle cable and see if it's better. Maybe new one is too long?

Did you ever notice those guys who had there throttle lever almost 90 degrees to the bar? That's part of it. Most guys modded the housing and lever so they could get the pull. The stock housing has the linkage and all that jazz inside is why the pull is so stiff.


I know I ground on the housing and ground the stops out of mine and it worked just fine. I had to do that on LTR's too.

Alright. I'll have to play around with it like you said. If you ever do get a chance to get a pic of your housing or one similar, I'd appreciate it.

Anything wrong with sticking 90 lever in stock housing and maybe cutting coils off carb spring?

I don't think the 90 lever will work on the stock throttle housing.

I always wanted to make sure my carbs would slam shut if I needed them too lol

And for the record. An ltr with a trx90 housing is dangerous as ****. You sneeze on the throttle and it's wide open. It tangled me up in down hill braking bumps more than a few times. Lol

Finally got shocks back. Have gotten a few more little things figured out and on this past month. Won't be long now.

Had a long hard fought battle with the motor this week. Discovered that it has a long rod crank in it but a 85 cylinder. So the piston was hitting the head. Ordered a spacer plate and longer studs and then got to removing the studs. The first 3 came out fine. Of course the last one snapped halfway in the cases. 3 hours of drilling and tapping later, I could get a new stud in. Spent all of today reassembling motor and putting quad back together again. Then got to hear the sweetest sound I've ever heard... she lives. Have 4 days to get it finished up for a debut at unadilla.

Guess I havenít updated this since finishing the build

Raced for the first time in a year, Ended up racing sport class at unadilla with 0 time on it besides break in. Ended up leading 3 laps until overheating and seizing it up. My fault for not replacing water pump when I had it apart

A bore job and new water pump went in and took it to a local GP race last weekend and had some fun. Struggled with getting stuck and crawling thru deep water holes. Definitely a fun quad and it wonít be going anywhere time soon but going to work on some fine tuning before breaking it out again next year.
