Wayne, where have you been?

I had to replace mine on the 1.25 Sherco about a month ago. The lower bearing was rediculously tight on the shaft. After cutting and splitting the old race off, the new one would not go on even after heating the bearing, cooling the shaft and polishing the shaft to remove excess material. Finally I used the old split race to drive the new one on with a hammer and drift so not to damage the new bearing. It was more work than I had planned that evening and I ran out of beer too! Real Pisser! Next time I'll have a proper length of crocus cloth to polish that shaft down to a nice fit (i think it needs about .001 in. removed). MC

I did forget to mention, if you ride a gasser,you need it on the INSIDE to keep the tire from rubbing a nice hole in the thing! Cheers, MC

Way to Go, CODY WEBB! Go Get 'Um Boy!

My God, That S---s! Thanks B! Let us know about tomorrow! Cheers, MC

I have seen others take thin alum. tread plate, cut to fit and screw it on. Reinforces the muffler too! Cheers,

ps- I deliberately excluded variables such as ignition timing and carburation to keep this discussion as simple as possible. plus- avgas is clean and stable for long periods of time neg- pump gas stinks and stains stuff and stuff(additives) will fall out of the fuel and "varnish" up components in the fuel system MC

I've never seen Ringo be so polite, so I'm going to risk putting in my 2 cents worth here just for giggles. Most "AVGAS" sold here in the US is what is known as 100LL, or 100 octane aviation fuel, low lead (blue in color). The "LL" part is relative, and is only in comparison to other aviation fuels which had a even higher content of lead (or T.E.L) tetraethylwhatever. Modern 100LL has approximately three times the T.E.L. content of what some of us remember as "leaded" auto fuel and is added primarily to help preserve the valves and seats in aircraft engines which were not designed to run on unleaded fuel. This LEAD serves no useful purpose in a two stroke engine! It can however in some cases cause premature fowling of spark plugs due to residules that may cling to them. It is the higher OCTANE(resistance to premature ignition) rating that is needed in high compression engines that prevents pinging and clatter due to preignition and detonation. I believe that most modern trials bikes are recommended to use between 93 and 100 octane fuel. Engine designs vary somewhat. EXPERIENCE: It has been suggested that EXCESS octane in your fuel does NOT increase available horsepower. I seem to recall that a recent dyno test performed by one of our resident members proves this to be the case and I believe it to be so, as higher octane fuel is basically more difficult to burn in a engine that does not need it. It has also been said that the higher octane fuels have a "smoothing" effect on a trials engine. I also believe this to be true because the dyno results show the engine to be producing less actual power. Go Figure! I have used 100LL in trials engines for the last five years with good results. Maybe I change "sparkies" every four months instead of every six, I really don't keep count, I just change them out if the bike starts getting a little hard to start. Speaking of hard to start, I have had some problems on hot restarts on hot days similar to what is known as "vaporlock"condition. I relate this to the fact that AVGAS is designed to atomize and combust well at lower relative temps(at altitude) than auto fuel. A hot day in Texas with a hot engine and a carburator on a Sherco sitting right next to the exhaust is quite the contrary! So I have been running a 50/50 mix of avgas/pumpgas for tha last year or so and it seems to be ok. I'm not sure what the octane really IS as I have read that it only takes 1/3 to 2/3 ratio to increase the octane, in other words, 1/3 gal 100 octane mixed with 2/3 gal 90 octane will yield 1 gal of 95 octane, NOT the 50/50 mix that you would presume! OTHER FACTS, As far as I know, RYP/SHERCO has been using straight pump gas for the last couple of years. I do not know if any other octane boosters are added but I'm sure Ryan would tell you. It seems that many manufacturers are either lowering compression or modifing combustion chamber design in an effort to allow the use of lower octane fuels. My old 98 Scorpa (rotax) would ping like hell if I did'nt run the 100 octane in it! Other engine designes may not be so forgiving, so you may need to vary your mixture accordingly, try it your self and see! So there ya go Ringo old boy, I hope that makes everything just as clear as mud! If you ask a fuel engineer about all this stuff you can't understand his reply any better than mine, the the end result is the same! I'm ready for that beer now ! Cheers, MC

OR, as Charlie was saying, due to sudden engine stoppage!

I rode it for a short while on the logs and it felt good and VERY powerful! I also managed to stall the motor trying to do a quick blip off idle. MC

How the heck do you guys stand that weather? It was near 90 F here today and sunny! I had to drink lots of beer to get through the day! Cheers! and best of luck to all the riders! MC

My Sherco puller worked on my ALP so it should be the same.

There are photos of everyone taken at the event, some really good ones too! Click on "find your event" then "April" then "Muenster National". Great slide show! Here's the link! Hope it works! Muenster Pics www.eventphotographyassociates.com Cheers, MC

Craig, Just be glad they toasted all the cow paddies or you would have had more problems in the motorhome than just the generator! I could have picked them all up and then shook hands with ya! Mark

Yea, Wardo, you shouda kept the Sherco so you will have something to ride while you're fixing the Gasser!

Thanks to all for the quick response, I'll give him the word!

Why on earth would you want to replace those things with originals(unless they are REALLY cheap)because they ARE really cheap! cheers

Is there something to the report from my buddy that his clutch engages too far out from the bar and will not adjust properly. He tells me that the screw has no effect? Someone tell me whats up so I can let him know! MC

Yep, rode both days last weekend and going back tomorrow to help set up for the national. I usually ride SR class, so the national sections are usually too much for me. Some sections I can ride, others not. As Muenster is our club sponsored event, I'll have to punch. I may go to Tenn. but I'll work there too:( I'll get to ride some though! Brad Villand came down last weekend with Ben Winterrer from Minnasota and spanked everyone! That boy can ride! HAVE FUN and say hi to Scott if you see him! MC

By the way, good to hear from you "ks", now stop listening to your dumb buddy Scott and go ride expert sportsman class and have a good time while he is getting his butt kicked. Them guys that ride expert in the nationals are too good or almost so. You should do well and have a good time! Enjoy!

Jeff, I'm going to try and make it, I'll send you an EM Mark

ks, you need to ride ES class and kick some butt. Try it out at Muenster!

ARE THERE RIDERS IN KS? WHO?

HA!!!!!!!

Haven't heard from her since she hurt her knee last year. Anyone seen her?
