2010-12 engine reposition

Recommended Posts

i spoke to the owner of lightspeed today when i picked up my engine reposition collars and he had a lot of interesting stuff to say. # 1 was that he has been in contact with yamaha and they recently tested the collars on stock bikes with different riders with pretty good results. # 2 was that he has been working with the yamaha race teams for over a year and that they have been running the collars for quite a while. they are installed on my bike now to be tested saturday.

I just put an extra link in my chain when i used a larger rear sprocket. Fixed my turning problems and wheelie problems on hills.

in my opinion they work. i kept my sag set at 100mm and didnt change anything else with the bike. i am running stock suspension with springs for my weight and a bridgestone m403 front tire. i rode today at elsinore mx and pretty quickly noticed that the front end didn't feel light and busy as before. i was able to push the bike more and my corner speed improved. the install took about an hour and was pretty east with basic hand tools.

I don't believe it lowers the bike, just rotates the engine in the frame. If you're trying to lower the bike you either need to have someone shorten the shock with a plate or get a link.

it moves the motor forward 2mm in the frame. you do have to file 1 mm away from 2 motor mounts. it isnt enough to do any damage, and can be reversed if you dont like the mod. i think somebody else might have posted that they weren't really meant to be used with any sort of lowering linkage or lowering shock plates. it comes with easy to follow instructions.

What is the location for the collars?

My wife was going to swing through Dubach Racing to pick me up a kit today. She called ahead and they said their first production run sold very quickly. Had to place an order. Second run is due in in about a week. I was hoping to install this weekend. I guess next weekend or the following.

Maybe some of the guys who bought the first production run will chime in about how they work. Thankfully they came out with a straight up bolt on kit.

BBrown, when you get yours be sure to update all of us

RIght on. I just ordered the Lightspeed kit. I didn't want to spend the extra 50 bucks on the DR.D kit. Hopefully mine will make it to me in the next week or so and I'll give a review on it as well.

I got the lightspeed kit with enzo revalved suspension that included the lowering plate. Will at enzo said they can be ran together. I immediately noticed the difference in handling and its a major improvement. I previously had stock suspension and the PC link which worked well but I wanted a suspension revalve. I removed the PC link and went back to stock linkage, and added the motor mount kit. IMO the PC link cured the knifing in corners, but the engine reposition kit with enzo suspension is even bettter for turning. I am much happier now. The filing in the lower frame was miniimal do to hole to bolt size tolerance slop already built in. The engine bracket filing was also minimal after loosening all bolts and moving the bracket before tightening everythign down. Eyeball what you need to remove and keep removing until the bolts fit. With play in the brackets it may be less than you think. It wasnt as bad as it sounds. Pretty easy mod for big reward.

Cant wait to try it. Considering either a pipe or tuner also. Anyone by Temecula/Murrieta have a tuner I can borrow?

      Selling an FMF Power Core 4 exhaust system off my 450FX. Exhaust has 80 hours and is 100% functional. This will also fit the 14-15 YZ450F and 16-18 Wr450F. If needed I can also include new muffler packing although it does not need it.

      I have a 2008 YZ450F with a stock header pipe and Pro Circuit T-4 Slip-On Exhaust. I'm 99% sure the slip on is shot because its loud as hell and when I take it off and shake it it rattles. I would repack it but the screws are all stripped ect.
      Anyways I've gone over the carb multiple times and I've got it running pretty well. The only issue I have with the bike is that it sputters and pops around 1/2 throttle when I hold it there. When I give it full throttle from any RPM it runs great or when I give it about 3/4 throttle it spins up like a top to redline.
      Initially the popping and sputtering was way worse I made the situation better by moving the pilot jet up in a few sizes from a 45 (stock) to a 62. The issue has gotten way better since then but I'm not super sure what to do from here. Should I keep moving my pilot jet up in size because that's a pretty large jump right? I tried changing my needle clip position but that didn't help much if anything it just made starting it worse and little to no impact on the ride.
      Any input on this would be helpful. I don't want to buy other slip on. Also as for the rest of the carb I'm very sure everything else in it is what it needs to be at. I've replaced all the gaskets and O-rings cleaned all the jets, valve holes ect. fixed the accelerator pump timing. I just thinks its strange that my pilot jet size is going so far from the stock 45, but all symptoms point to the bike running lean.

      Hi I was wondering if y’all have been using a 450 on your YZ250F?

      Excel Takasago 17x3 front and 17x5 rear supermoto wheels with Metzler M3 tires in very lightly used condition. Less than 200 miles total on the setup. Warp 9 spokes. Rear has a Talon hub with 45T Sunstar steel sprocket and OEM rear disc, and front has a polished OEM Yamaha WR450F hub (for the stock speedometer), with a Motomaster 320mm disc. Included is a DID gold o-ring chain, 14T front sprocket, and front brake caliper adapter for a truly turn key setup. Everything is in excellent condition, not a single scratch on these wheels. Came off my '11 WR450F, but will fit many different Yamahas with 20mm front and 22mm rear axles. Asking $1400 plus shipping.
      **Will be driving up near Atlanta, then to northern Louisiana, OKC, and down through Dallas and Houston, TX soon -- can meet or deliver if in the area (Aug 31-Sep 9)**
