I just aquired a bunch of total loss stuff in a lot of parts that I bought. One set I'm pretty sure is of a yamaha 701 but I can't find anyone who can help me verify it. I need someone who might have a flywheel on the bench that can give me some measurements like the outside ring gear diameter...

Anybody got the starting for jetting dual 44 mikuni red tops on a small pin 750. I've been told you have to run a bigger pilot than the main. Anyone else got any input . Please help!!!!!!!

speedsupplies.com offer all kinds of obsolete parts. You can even order on line like they have them in stock. Then you wait and wait and never see your parts, They even send you an e-mail to confirm your order. After numerous e-mails and then a very threatning letter they told me the parts were...

I just built a new motor for my blaster. I used 62T cases and a 61X ported cylinder. Right now my boat is built with a 62T/62T motor and a FFP maifold and mod pipe. I have heard that there may be problems using the exhaust manifold on the 61X cylinders. Is this true? what do i need to look for...

The quote below is from MSD. What it doesn't say is what is extreme compression? 200 psi? or low octane 89? any one know? The timing advance plate is recommended for all Kawasaki® 750 engines running the Enhancer Ignition. This plate advances the timing 7° for a boost in low to mid range...

Two of my skis are experiencing the same problem. Both skis are running small pin 750 motors with 750 electronics. Both will only start when I let off the start button. If I just crank on them they will not start, but as soon as I let go of the start button that is when they start. They both...

OK I'm baffled. I was riding my 750 x2 today and it just quit. I took it home and nothing makes sense. I have 180 psi in both cylinders good bright blue spark and fresh fuel and it won't hit a lick. I even tried some ether and it wont hit a lick. Pulled the flywheel and checked the key and it's...

I have a blaster 1 with 701 and a mod pipe. I just bought a set of v-force delta 2 reeds and the instructions say it may require re-jetting but doesn't give a clue as to how much difference. Any one havce any experience with installing a set. Did you have to re-jet? if so how much bigger did you go.

I finally got the 94 Blaster running right. It had absolutely no bottom end power. Looks like it was a combination of pop off and water setting on the mod pipe. The FFP site calls for 115 gram springs on the twin carbs. All I can say is that's way too high on this set. Cranked in the water...

I have a 94 blaster 1 with a 62T motor FFP mod pipe, no port work, and twin 38 mm Mukunis. I set the jets up like the Factory web site suggested. 140 on the main 70 on the low side and 115 gram springs, stock needle and seat. Engine is new rebuilt so I know it's tight. 155 lbs per cylinder. The...
