Drop main to 300. Test again.

When they be done?

Big bore pipes?

Billet?

Too many ordeals with people. Misrepresenting for sale ads. Wouldn’t change them to accurately depict what people were getting. I gave them an opportunity to remedy it, but no changes. So I booted them.

Stay away from them. Driveline makes their own cases and cylinders. Give them a call.

CST Pulse

We like new people here, but you can stop pretending GRR has done anything notable in the last 10 years. I venture to say that anyone new to the sport in the last 5 years has never heard of GRR. That's a fact. So, my advice is to do something. Then post about it, because you aren't fooling anyone posting here. Or you can try the FB group, but I guarantee you will get a lot of "never heard of them" comments.

Fireball is absolutely top notch and comes complete.

That might be what it comes with but that’s not what the motor will need.

Sand or dirt?

If it’s coming from under the nut, put 1211 inside the nut and tighten down. DM cylinders will leak there if you don’t seal the nuts. It’ll seal.

Can you see the case bolt on the inside of the intake?

1211 is sealant. Same as Yamabond. The intakes bolts hold the intakes on.

Whoa whoa whoa. Those are not even close to the right jets. Do not ride it. Start with 165 main and 52 pilot.

Put the domes in. Check compression. Jetting shouldn’t change much if at all. You need to make sure you’re under 150 PSI to run pump gas.

I run a +4 on mine.

Stock. Or 28mm PWK if you need to buy some.

Get shorter intake bolts. Put 1211 on them and run them in. Problem solved.

It sounds like a pulse line for a fuel pump. Post a picture.

What size domes? If they’re 22-23 then that’s likely normal at that elevation. If you want more compression, swap domes.

165 mains. 48 pilot. The pilot should be about right on. You may need to drop the main a little.

They can last forever. I did a few back in the day. I’d still recommend just buying a new arm and being done with it.

Stock is 25/210. FMF will likely fall about 27.5/280. Pipe performance is directly related to the motor build. There is not one pipe that will work on every motor.
