I currently have Northwest sleeves. Bored to 85.5. I am not looking for freestyle.

How big of a stroker can you run on an 62t cylinder?

MMS & Accessories (800) 441-9451 They are located in Rydal Ga. I have bought stainless allen heads for the b pipe head pipe.

Well on Yami's site it says 1.0. But the ones that were on the pump nozzel looked to be very thin. So I would say .25 for those.

I had to thin pump shims on my 98 Super Jet. One on each side. I lost them. I was wondering if anyone had 2 of them? I looked on Yamaha's site and it shows you have to buy them in packs of 10. It says they are 1.0mm. Thanks

What is the thread pitch on the cylinder base bolts on a 98 SJ? Is it 10x1.25 or 10x1.50?

I have a call into Tim at Novi. I don't have a 140 but I do have a 130 main.

I am going to go with 3 gallons of 110 and 2 gallons of 93. That will take it to 103.2. With 195 psi I will need 98.5 octane.

#0 according to my sheet here from Advent I have 30 at 5000 rpm still and at 7000 I have 16.4. I am running gen 3 48mm Novi's with 140 pilot 120 main 2.5 needle and seat 115 spring 20 psi pop off. lo out 1.5 and high out 2.

Last week I only ran about 2-3 gallons of fuel through it. Do you suppose it started last week? The flywheel is the newer TBM wheel that works with the Advent.

What is cylinder stuffing? Also what would cause the sudden free rev? Thanks crammit442 youre always very helpful.

I have a 5mm stroker with 85.5 bore running 195 psi. I was running a MSD enhancer and a b pipe with 93 octane fuel and a bit of octane booster and everythnig was fine. Last weekend I switched to a type 9 pipe and a Advent T 3 ignition and a oem flywheel. It ran awsome. This week I added water...

That sucks could have had mine. But there gone

I am running a type 9 dry pipe which has 1 water line going into the exhaust manifold and the other into the pipe itself. My question is can I tap the line going intot he pipe for the h2o injection? It is alot easier to get at than the other,

I would just like to see a pic of some ones hood underside. I cut out a bit but it is still rubbing. I can hear it vibrate gainest it. Wax? Wattage?

I just took my 98 SJ out today for the 1st time with a Type 9 and a advent ignition. All I can say is WOW!!! It had all the hit of the b pipe and pulled like crazy on top. With over half a tank of gas I gpsed it at 58.3mph.

I just added a type 9 and an Advent. I am running 48 Novi gen 3's. The carbs are 1 1/2 turns on the bottom and 2 on the top. If I prime it it will start. After that fuel burns off it will not stay running. Any ideas?

I flipped flopped some red wires now I have spark.

Yes new right out of the box.

I got it to turn over but now I have no spark!!
