Tires...

DirtHog350,

I haven't used the Mud Lites, but several on the Board have. One thing I have noticed is that a lot of members end up with a tread which is of the "curved V" variety.

When I first changed out from the OEM tires I was concerned that the larger gaps in the "V" style treads would be a problem when the bike was leaned over in a sharp turn. Turns out that isn't a problem. What seems to be key is that the tread wraps down on to the sidewall a bit.

Maybe the base flotation from the large tire size is the source of the squirrelly-ness and the aggressive treads provide enough of an offset.

Chain gaurd woes

Anyone have a used one with the metal piece that goes around the jackshaft sprocket? I caught a stump bent it, threw the chain that wrapped itself up like a snail in crazy glue. Had no tools with me (I know) and had to pry it back with a rock and a few good kicks from my tooless companion. had a great day of riding after that but my boot heel keeps hitting the chain. Se la vi.

Rear Tire Woes

I read with passing interest the tire discussion last week. After a weekend ride and slashed factory rear sidewall later - - I'm feeling the pain. Now, I gotta get a tire, too! I've seen reference to these tires elsewhere and was curious if anyone bought, installed and rode. STI Black Diamond ATR Radial ATV Tires, D.O.T. http://www.pureoffroad.com/sti_black_diamond_atr_atv_tires.htm

While not important to me, they are DOT tires. They LOOK like rounded profile tires. I'm thinking the 25x12R-9 as the size. I'm concerned about clearance. I ride mostly flat trails on this particular bike in Texas. I'd say it's pretty tame riding. I'm more concerned about reliability and less so about squeezing every last bit of performance out of the bike. Any thoughts or alternative recommendations?

STI ATR Tires

I have a mounted set of STI ATRs waiting to go on a BW. I can take some photos and post later. The front is the standard 25x8-12, but the rear is a 23x10-12. Those are radials, so my expectation is the ground contact patch should be larger than a bias of the same size. The 23x10-12 looks to be about the same width as the OEM rear tire as mounted.

If you are willing to change to a 10x10 wheel, you could go with the 24x11R-10.

All of those tires are 6-ply and a bit heavier, but should work out great - especially for the plated few.

I am using the Carlisle AT489s on both ends and the difference is remarkable in terms of tracking. -Not to mention the tendency of the OEM's to become "mud slicks".
what sizes are you running with the carlisle?

Carlisle AT489

I currently have a 25x8-12 on the front and a 24x11-12 on the back. Both are AT489s.

If you include the 10 inch and 12 inch rims, the tire size options increase. But, the other size rims must be re-drilled to the BW pattern.

The sickness is complete

Went to AMA vintage days and took the 200. Saw 1 other 200, about 3 80's and no 350s. Made a deal on one of the 80's and it carried my 250 lb butt around the track for the next 12 hours. Should have brought a clown suit to complete the presentation.

BW200 Carb Bowl Drain Plug Screw

Does anyone know a source for the OEM carb bowl drain plug screw? (This is listed as part number 11 in the Yamaha parts diagram for the carb.)

I have one on which the cone shaped gasket is damaged and will no longer seal properly.

The parts sites I have checked don't show this screw or gasket as being available. I thought perhaps someone knew of another carb which used the same drain plug screw.

I'd love to see those pix as I'm getting to street my 350. Getting ready for when the zombies march on Brooklyn. I thought they already had but soon learned they were hipsters!

Wingnut..Did you check with NY Dept of vehicles? dot rated are probably needed for your inspection to pass as it has been in most states that allow conversion of 'dirtbikes' to street legal..are you doing horn-blinkers-reflectors-mirror?
There are dot rated tires that will fit ..
