About $500 too high.

I would recommend draining it, and pickling the engine with regular fuel. I left it in one of my bikes for about a week and the fuel and vent lines got VERY soft.

You can't buy pump gas with less than 10% ethanol in Texas.

The increased temps caused by the coolant leak killed your piston. The increased compression from the big bore didn't help. Broken ring lands are caused by detonation. If you learn what it sounds like, you can save engines before you break parts. If ... more »

I think the Ti YZ/YZF pegs started in 05. Pretty sure they are all the same.

Hey Mike, I highly recommend that you check your radiators before you ride your bike. I went to the track to test my 87 last weekend. I have a temperature gun and it was getting up near 200 degrees in just two laps, so I packed it up and went home and ... more »

He's not super tall @ 6'-3", but he has a long torso and he rides sitting straight up, which looks odd.

Standard CR250 clearance is .002-.0026" and the limit is .0033".

The A cylinder and the B cylinder have different part #'s. The cylinders are also marked.

It seems counter-intuitive to assemble the piston dry, but it simply works better. The first time I read about it was about 30 years ago, when Vic Krause ran back to back tests to prove engines that are assembled with dry pistons have better ring seal ... more »

Honda B pistons are smaller than their A pistons. As far as I know, they are the only manufacturer that reverses the logical order of the piston sizes. The reason they offer two different sized pistons is to get the piston/cylinder clearance spot-on ... more »

Thanks for the hook up DJ! I really need to get down to 3P this summer. Maybe we can hook up there.

2-stroke pistons should be assembled dry. 4-stroke pistons should be assembled with a dry lube, like Total Seal Quick Seat. If you oil the piston/rings on assembly, you'll inhibit ring seal and reduce power. Break-in should be short. A few laps of moderate ... more »

BTW, it turns out that the YZF rear spring won't work on the 87 CR. That looks to be only a 88-96 thing. What Race Tech lists as the replacement spring has a too small ID on one end. There's nothing off the shelf that appears to match, so it looks like ... more »

Hey Mike, I looked at the springs on my '95 and they'll work for you. I put a 95 peg on my 87 out of curiosty. I liked how the 95 pegs move the pegs back, but they are about 8mm taller, which won't work for me. Somebody installed some peg wideners on ... more »

I like your story.

Who rides a 450 in 1st gear?

I knew that wasn't your handiwork! I haven't finished my prep work yet, so I haven't hit the track. So far I've got the new case cover and fork boots installed, and I stripped off all the stickers. I have a Ti YZ450F spring in hand and a matching set
