i removed the spacer on the reed block but found the carb is short of the air box.

Mount the carb in the airboot, heat the airboot good with a hair dryer to soften it, and pull the carb into position/mount to manifold coupler. Continue heating evenly for a minute or so. Airboot will take a set in the new position. There is only one airboot, yours has taken a set in a compressed position from the spacer being installed.

That's scary. I'd hate for my newly spacerless and re-set boot to decide to re-take it's old set in the middle of a dusty trail.

Like GMP said. They will mould quite easily. I did this when I removed my spacer. No issues with it changing during a ride.

What do the spacers actually do? Someone told me once they boost bottom end?

I had to replace the airbox on my GasGas 01 xc300 the original got destroyed by a tree branch harpoon. Ever since I got the new airbox I've had to fight to get both ends of the carb sealed good. Currently its not straight in the coupler to the reed block. Away on vacation now bike is with me set to go to my riding camp this weekend. Will try the hair dryer trick once I get home again.

Thanks for the info, Tim

I don't think they boost anything, they soften power. They add crankcase volume to the 300, which shares cases with the 250. I tried one in my old '00XC250 and took it out immediately.

[gassergrant]

all done, tha air box thingy was really soft and went in to place with out a fight got the hair dryer on it just tomake sure

Some say the spacer boosts bottom end while taking away some amount of top.

The two-stroke engine (plus intake and exhaust) is like a wood wind instrument. Adding or subracting lengths or passage ways changes the "tone."
