well I'm doing a total rebuild of the motor, since when I got it the engine was in pieces, and I'm not digging how much play is in one of the crank bearings. the crank itself is ok, but the bearings, are toast. at least everything is nice and clean.
how much more power does the 101 kit give? and is it reliable/affordable? I have no worries it'll be a good bike, hey its a HONDA. these things are tough as frikkin nails. |

http://www.eric-gorr.com/porting.html Basically the cylinder is punched out to 52MM (stock is 47.5mm i think) and the ported like a monster to flow way better. This will make it a 101cc. To get 105cc or higher you use same piston, but put a stroker crank in. 101cc is pretty reliable and with the ported cylinder she rips. I should know, because i can get on the stock refreshed CR85 and then on the CR101 and there is no comparison. You have to watch the temp on the 101cc and keep her moving or she will overheat. We run FactoryEffex temp gauge stickers ontop of the radiator and the side of the cylinder to keep and eye on temp while son is on the starting line. We also bought an aftermarket overflow bottle for the radiator to catch coolant if she gets hot so it can suck it back into the radiator as it cools down with air movement thru radiator. I don't care if the crank looks okay, if the bike is old replace the crank/rod combo and main bearing and seals. If i recall the crank kit comes with the bottm end gasket kit, seals, bearing , crank, rod, and upper rod bearing for less than $170 Check out wiseco stie http://wiseco.com/ProductDetail.aspx...994&AppID=5986 Kit includes: Crankshaft B1012 - TOP END BEARING 14 X 18 X 16.2mm B1045 - CRANK PIN BEARING - 20 X 26 X 13.8mm B5009 - MAIN BEARING 22 X 56 X 16MM W5763 - THRUST WASHERS(2) 20MM ID X 1MM W5789 - CRANK PIN - HOLLOW - 20MM X 45MM WB1012 - Bottom End Gasket Kit- '86-05 CR80/85 Last edited by Thumper996; 01-24-2010 at 12:34 AM.. |

You can get the crank kit off ebay with the bearings and gasket kit for around $137 to your door.
http://motors.shop.ebay.com/i.html?_...&_sop=15&_sc=1 Seriously, if you have not bought any parts yet, this is the way to go. By the time you buy bearing, seals and gasket kit you are going to be half the cost of this kit, why not take care of the crank now and do it right. It's what i did and will do on the CR80 and CR85 when they are ready to be refreashed. Even if you don't do the Eric Gorr 101 route, you should still replace the bottom end. seperating the cases is the hardest part. The bearing can be tricky to get our of the cases, use heat and freeze the bearing to put them back in. Last edited by Thumper996; 01-24-2010 at 12:42 AM.. |
