You can do it without welding but you have to be REALLY careful.If you weld it you can go ALOT bigger.

I agree with what you said 100%,but it use to be alot of fun and a since of pride to port my own cylinders and see how they ran against the competition.Go out and get beat, come home and rip of my cylinders and try something else and see how it worked.But if you are not into tearing your bike apart all the time and don't want to risk a set of cylinders then having them done by a pro it the best route.That use to be half the fun of riding for me,now that i am older i just run cp cylinders and let the pros port them.(Redline)

I think at that elevation you would be ok with 93 octane but at sea level you are on that fine line.imo

Did you add the idle screws when you removed the T.O.R.S.? You have to drill your carbs and add idle screws. You could try pulling your choke out when your bike starts back firing and see if it changes anything.This will help you figure out if it is a fuel problem or an ignition problem. Also what pilots do you have?I would run 27.pilot. When you do a plug chop do your plugs look golden brown?

T-5s hands down.T-6s are a waste of time and money.imo

2-5 duneable with 1st and 6th removed.

No worries

I have fucked up some of my own cylinders that ran real hard.

Redline sells duneable overrides for $400 and he cuts his own. One of the best mods you can do to your bike.imo

What size pilot jet do you have?

Since you have the 42 rear with your set up and only 20 inch tires i would try a 14-42.If you cant launch in 2nd without bogging with 14-42 you could go up to a 43 in the rear.12-42 with a 20 inch tire is crazy low geared. You do not want to shift into 6th gear at all, you want to be wound out in 5th gear when you cross the line, so try to gear for that with a 2nd gear launch, with no bog,feather the clutch at the line if you have to.

What do you think people used for drag pipes before all these other pipes were so avalible,myself included? O yea cut t-3s and T-5s when they came out.

I would just re ring it and hone it like you said,if everything looks new you should be good to go. Your compression loss was the bad oring, you might not even need new rings if you are on a budget.If you put it back together and don't like the compression then you have lost nothing but a little labor cause the coolhead o rings are reusable if they still look good just use good grease.

AMEN.

Like i said PTs look good, Cascade builds really Nice looking bikes not FAST bikes.imo

Just pull in the clutch after the run and click it down to first while you are still rolling,use your brake and come to a stop or slow roll and let out the clutch and leave it in first. I run a duneable overide so i can backload mine some but the drag only style you can't.

I think it is the 1 1/4 inch handle bars Could also check plug caps.

I would take T-5s ALL day long over PTs high revs. PTs look good but that's about it.

Do you also have the trinity domes?I WAS running trinity domes at one time and i kept having problems blowing o rings and detonation problems,i switched domes and problem went away.I did not switch dome size so i think they have a bad design.imo

A duneable over-ride trans is one of the best mods i have ever done to my bike, if you don't have one you will be at a BIG disadvantage cause alot of guys have them. You can downshift and backload a duneable.

If you go bigger on the back sprocket then it will gear you lower and give you more bottom end grunt,if you go bigger on the front sprocket it will gear you higher and you will lose on the bottom and gain on the top. Adding or subtracting one tooth on the front is like adding or subtracting three in the back.

All that compression will def kill your over-rev,i use to rattle plugs loose with 18cc domes on alky, i put in 21cc domes and pumped about 180ish at sea level and my bike ran alot harder and ALOT more reliable. You should lower your compression and run more timing.

12-42 gearing????? Thats whats killing you. Wayyyy off IMO. X2

Make sure the screens on the petcock in the tank aren't full of crap,and also make sure your fuel cap is venting good also.

Paul Turner high rev pipes would not be my choice of pipe for drag racing and hillshooting in the sand. I have never ran a set but i also have never been out ran by a set either. I think T-5s will out run high revs, not to mention the cpi,shearer,rockets,fat bastards, a little off topic but it sounds like you are trying to get all you can out of your bike after seeing all your other posts.IMO
