Has anyone used Glucosamine with success? Joint maintanence.

Runs perfect! New top end, eliminated oil injection, One super happy kid yesterday. The largest problem was solved with a giant bonfire, there was so much sludge in the exhaust I tossed the little muffler in a giant fire, burnt that baby but good!

I purchased a new piston and ring set for this bike, also in the set is a spring looking part that must go under the top ring, is this necessary on a freshly bored and honed cylinder. I've actually put this mini-bike on the back burner to fiddle with a new sherco!

I did a compression test by putting a little oil in the cylinder, the reading is the same, 90-100. But, then I took off the exhaust and the compression test shows over 120-140lbs. So. is this a sign that the exhaust is plugged?

YZ 80! Cylinder bored, new piston rings and yet after 7 kicks the compression only reads 100lbs. The bike actually starts after a couple kicks, Idles well, but no power. The reeds looked clean to me, after 45 min of riding the plug looks half black but dry not wet at all! Also, I checked for air leaks and did not find any around the outside of motor. So, what now? engine seals? If a exhaust is plugged up can it effect the compression? Mean while I have done the whole top end on my Montesa and she runs great!!! sam

So, they are very close to the GG? Thanks for the reply. sam

2007 290 Sherco's weight?

I have a cracked Airbox right underneath where the fender attaches at the rear on the left side at the tab/ear like portion. Its actually a large gap, is there anyway I could plastic weld this back together? New air box cost 200.00+

Very easy to take apart the oil injection pump, thanks again for the help! sam

Well, I still think the Shoei is Stylish!

Shiro or Shoei, I can not decide? The Shoei seems to be the sharpest looking lid!

Thank You for the Reply, Sounds easy enough, I'll give it a shot and thanks for letting me know about D-Kirks having gaskets. Bike bandits has been real good, downside is the location is on the west coast. I'm spoiled with companys like RYP, order today, get it tomorrow! sam

Kevin, Is this gear pulling of the auto pump for the oil injection easy, you say place a piece of metal to plug the hole, sounds over my head, but I'm going to tear into it today, imagine I'll need a new case cover gasket? looked at the schematics on BikeBanditos, many parts to that little oil pump!

I never thought of that, flipping the tire is a great Idea!

Sergio, Thanks for all your pics and vids, they are awsome! sam

Me to Paul! I was walking a section on the first loop and fell down on a greasy bank, dislocated and fractured my middle finger! I think actually a Sherco pilot pushed me, but it happened so fast no one would fess up! I know one thing, I was told that I was hopping around like I had been snake bit or something, embarrassing! sam

Paul, Give us a report! If you google tire cutting/sipe there are various places to buy them on the net, cost 50.00-80.00 scahoots!

Sectionone, I think you are right, once you carv into the tire it would shorten its life span. I was trying to sharpen my tire last night with a filet knife and stuck a knuckle, that hurt! My wife asked if I had crashed off my stationary bike/Rollers in the basement again! sam

Do you have any good Ideas for cutting edges on a tire/sharpening? I keep looking at the electric fish filet knives at Walmart, anybody tryed one? The tire cutting tools I see sold on the various world wide web stores look like they are for off road 4x4 truck tires. sam

Not garbage, fine obsticals!

I will check the Flywheel for movement, but hoping its just all top end! I'm probably going to buy everything from Bikebandits, Are there any other parts people out there equal to Bike Bandits? This bike is I'm sure a 74 YZ 80, grey tank red swoosh, the tank looks the same on the parts breakdown sheet, all the pictures are black and white though. Wish me luck! sam

How to test compression on a motorcycle= http://www.dansmc.com/compression_test.htm Yes, Paul I think I need a rebuild! Thanks again for the tips everybody!

Chris, Can we drag garbage in the horse arena to ride on? sam

Thanks Paul/lineway for the tips! I can not remember how to do a compression test? 1 kick shows 25lbs-2 kicks shows 50lbs-5-10 kicks and she tops out at about 80lbs. Is this correct? I replaced the cylinder head today, she will not start. Checked plug and it looked like there was crank case oil on it? If the compression is bad, does this mean the rings are cooked or engine seals are also a scenario? Before I had the head repaired, she would start and Idel just fine, but give it gas and it would bog out, no power! So I sprayed brake cleaning fluid around looking for air leaks and located this huge leak around the head, could actually stall out the bike. Lineway, I almost picked up some emory cloth thinking I could level it on my slate counter tops! This little bugger is a puzzle? sam
