Wilsons Sandbox

Hiya all. Been browsing the forum some since I got my KL250 SuperSherpa G4 back in June. Couldnt help but notice all the 'doohickey' related threads, but I havent really read those, not enough to even be sure exactly what a 'doohickey' is. Friday I snagged a spare bike. 93 KLX650c. My question is do either of my bikes have a 'doohickey' ? or can I safely continue ignoring those threads. Got service manuals for both, but 'doohickey' dont show up in the index... Thanks

Thanks Kurt for the carb modification suggestion. I took the plug out today and the popping from the Supertrapp seems to have stopped. Probably the simplist modification there is but I did not know about it! Thanks again! Jim Davis
