The things have enough power for what I will do with it. But you know once a gear head always a gear head.

You think it's easy for me to say "Don't do it. Don't spend that kinda' money on a $1200.00 motorcycle?" You don't think I'm waiting for one of you guys to say, "Screw you, ARH. I'm dieing to know how far we can twist this little tigers tail". And if someone is thinking about doing this, remember months ago I said buy another head to play with, and that advice still holds.
Besides porting, rocker arm ratios can be tried. Squish bands can be welded in the head. A bigger inlet valve, with a five angle valve job could be in the works. Wish I was younger, I'd be on this like a hound dawg on a meat wagon. Do you guys really think that we just went out and bought a Goldstar and magically won races? My flow bench was real crude. The medium I used was cigarette smoke. And the cylinder was plexi-glass. With a piston in it. BECAUSE I HAD TO KNOW!

If you haven't already, drop those forks down in the triple trees. They push the front down and slide the forks up in the trees for shipping.

Yes I did

I'm also gonna be testing the handling max speed today aswell! I uploaded a picture of the forks! Raised up and also gave some input if you refresh the page when you're here it'll reload everything and then you can see all the post (new ones)

The Kenda K270 or Shinko 244 would be good for this bike and supposedly last a good while.

jdogg=Azule or however he spells his username here. I'm also a dog and I can't spell but I can modify ruh ruh to a growl, bark or a happy squeal. I went 16/44 with my gearing because Bismarck is not flat.

I'm gonna keep the 15T (in case of chain break) also gonna put a 40T on rear for faster top end!

I will sacrifice the low end, but eh, won't really be doing to much trail riding and if I do just swap it back out, and have an extra chain for the correct length! And keep the tires I have as backup for trails!

The 40 tooth will still be good for off road too. I have the same combo and works great. You could always put a 16 or 17 tooth on front if you don't plan going off road.

Hmmm. Do you think it would be better for top end? Ok I'm not gonna be a speed demon on this, I understand that, but I would like to achieve a decent amount of speed and I know I didn't pay for a racing enduro or anything, but I want 70mph to be achievable and cruise at it not for highway just for my liking is all. What do you think gear ratio would be best? Mr.JerryHawk250!

our cops here In our area are pretty cool! Luckily!

timcosby · 02-06-2017, 08:57 PM

im running a 17/50 combo and cruise at half throttle at 55-60 so i would think the 17/40 should make 70 cruising about right. they are cheap so i would try the 17.

Be gentle with this bike until you get it broken in. They start to come alive after 500 miles. When you put that 40 tooth on, better re-jet the carb right away. You will be running a lot above 3/4 throttle, if you want to stretch it out to 70 mph. And Wide open throttle combined with a tall gear ratio, and an over-lean carburetor is a recipe for disaster. Engine melt down type disaster.

15/40 is a 2.66 final drive ratio. Stock is 3.33. I would think that 15/40 would work really well for your mainly on road uses. If you live west of Fort Worth, it might be too tall, going west from there. I once hauled 45,000 lbs of iron out that way, and my Double-Breasted Yamaha couldn't pull it in top gear. Had to run in ninth all the way to the escarpment over the border in New Mexico.
