Expansion Chamber System Recommended for Grube 49cc

[gearhead222]

Dear Fellow Members-I have a stock exhaust on my 49 cc Grube 2 stroke , mated to a 26" Huffy Cranbrook Beach Cruiser. Am wondering if there are ANY expansion chamber exhaust kits out there that mate to the engine with no fitting mods. Looks like I can choose this:

What worries me more is needing to buy the 2" finned extension to get enough ground clearance, which costs around $40.00! Here is that:http://www.ebay.com/itm/321387939575?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT

Dear Fellow Members-Received my expansion chamber exhaust and it's sweet! Any recommendations on how to secure the exhaust to the bike so as not to crack any of the welds? I used some scrap aluminum on my stock exhaust and am thinking of using a ring clamp on this new exhaust, with perhaps a bolt in the middle Again, any constructive feedback is always appreciated Gearhead222

Got the exhaust system and it appears that my Grube sits too far forward, as the expansion chamber is maybe 3/8" away from the front wheel-too close for comfort and not enough nipple to make it worth bending, IMHO. Sent back-Gearhead222

i was going to say, bracket, half wrapped around, with extension spring to hold chamber in tight... and some type of spring at the header join as well...


now all i say is ha ha

Hey Jester! Nice job with the bailing wire! Ya' think that your throttle cable is long enough? Love the spring loaded idler wheel!

 

[HeadSmess]

observant!

its the stock tensioner

i couldnt be bothered finding the sidecutters when i did that throttle cable so wind it up i did should see the clutch cable! thats mostly on the bars...

previous attachment. i also couldnt be bothered taking a new pic! the wire isnt tight because it was to stop the thing twisting more than anything. now it has a bracket as described above. few years ago now. still going strong

Looks like shyte Yah, I know it's the stock tensioner- I was being sarcastic-BTW, they suck. Been using a spring loaded tensioner for the last three years-Gearhead222

good for you

the shyte appearance prevents people from taking it the colour of the new (though its also the old, just resurrected) frame also helps double butted cromo, nice




ill keep my springs where they're necessary, holding down an exhaust so it doesnt break off






and keep my solidly clamped tensioner where its required to stay stationary




though i will use a spring tensioner on the other side, as MTB frames dont allow for moving the axle to tension the chain when running 3 speed hubs




due to accidents long ago, the derailleur mount was twisted, ruining the thread. theres a reason they use replaceable mounts on most frames now
