Hawk, TBR7 and Magician top speed averages. - Page 3

My big butt likes the 2.6x range as well, and it works good for a mix of flat land and moderate hills.

As far as the 520 and the 13t front sprocket. Results may vary. Mine fit just fine.

I have a stock HAWK meaning I only have the air box and carburetor tuning modifications. I have a 520 chain and had the 13t 35t ( 2.6X ratio) installed for a short while and I will say a great ratio no doubt. The first time I shifted from 1st to 2nd I thought wow you can wind out 1st gear and 2nd is sweet on rpm too, but I live in mountain country and the flatland quickly becomes hilly and then mountainous so power up a grade is important. What I found navigating up some fair sized hills compared to other ratios was a greater loss in power and speed with the 13t and I weigh 180 lbs. I have an 11t installed now (courtesy of Dan's research) which figures 3.1X and I can run almost the same WOT top speed of 60-62 mph AND it maintains greater speed up the hills than the 13t apparently better utilizing the stock engine band power output.

I think its the Uni-Bear chain. Mine was ever so slightly rubbing the cover with the 12 tooth on it, and it definitely wasn't going on with the 13 tooth.

13t can also be solved with the 520 13t reverse keeper installation which requires grinding the sprocket cover. I found it runs great that way and I install all my sprockets in reverse keeper to get good clearance from the case. 13t is too good of a ratio to let the issues stop you in my opinion.

on stock bike with stock sprockets, my hawk would top out at 60 whether alone or 2 up. now it tops out at about 75 with myself and 65 2 up, at a much nicer rpm. I weigh 165 lbs. I currently have it at 17/44,

Nah, the way mine was rubbing on the inside front of the sprocket cover there were 2 distinct lines with the 12 tooth. Flipping the sprocket wouldn't have helped. That being said the Uni-Bear chain is bigger and bulkier than the expensive 520 chains I've got on my quads.

if anyone can help please. tried to pull out the screw to see top dead center and i guess it was too tight idk it stripped out. any ideas to get it off? reason im doing it is because there is a quite a bit of ticking coming from valves. how much tick is too much?

Uhmm..

This thread has nothing to do with valve adjustment. Please use the search function and if you can't find an answer we will gladly assist you on an appropriate thread. Or start a new thread, that will probably get you quicker results.

Makes sense. Two ways to get strength. The cheap way, which is more of lower grade material. The more expensive way, less of a higher grade material.

Uni Bear chain is a fine choice and good bang for buck on China cheapo bikes.

I personally suggest that over say a fancy big brand 428, so I suggest a mid level 520 chain n sprockets

You can add another Bashan to the Hawk class at max 64 mph. 17/46 is the gearing. Rider is 200lbs with 30 pounds of TKC80 100/120 knobby wide tires.
