well she's about done, It's time to bring everyone up to date What we have here is a 1984 spree nq50
THE GREEN HORNET 34-35 mph he he he for now!
getting decals made!!!
whats been done -
tazlands 44mm big bore <--------- fantastic
head milled to big bore spec<-----------great job done by toboggan
95 jet in carb - 5 -1/2 inch holes in the top of the air box
opened more volume in the top of the intake by grinding out some material
stock pipe went through a cleaning by wood stove--get it real hot and remove from the stove TAKE OUT SIDE and blow air from a compressor into one end and the rush of air will burn a lot of carbon out - reheat and blow in the other end do this till you feel that its lost some carbon. I tap it with a screw driver it should sound tiny if it sounds like a thud it could be more carbon
replaced the side cover with a kicker cover from and 86 ......be careful if you buy on ebay the kicker sides don't ever seem to be sold with the kicker flywheel and its a must!!!!!!!!!!!!!!!!
starter and bendix from the 86
tazlands big bore gave great torque so
shaved the front pully (used a 86 it has more meat on it )I added 1 washer on the front of the flywheel (this mod also helped my starter catch better as it brought the flywheel closer to the bendix)
went to a 1/2 - 25 gates green kevlar belt
tazlands big bore gave great torque but if you don.t feel you have the power try the belt first its 12 bucks. I have a lot of pulleys so i didnt mind cutting one . I love the having both. with 2 belts -one new stock and the gates upgrade and 2 pulleys one stock and one milled there is a lot you can do to the power curve ... but first have your suff tuned in. the results will be worse if you cant make good power
BELT!!!!
I had a worn belt and was getting 27mph after the belt and pulley mod i was up to 34-35
new battery
massive repair and re-tape of the wire harness
complete strip to the frame and repaint frame, rims and forks w/protective black enamel forks bearings removed and repacked
remove stock pet * and then went to pre mix 32:1 after break in. connected both ports on the intake together wit a short tube. why waste vacuum on opening the diaphragm now i use the oil tank as a reserve tank
no back plastics so why have fronts
chopped the back fender (i love It)
the front is next for reworking !
whats up next
new tires - I'm going to 10x3 street tires
custom turn signals
hard removable saddle bags
new seat
tazland's new gears when the money's there
port the exhaust
AND
using the expansion pipe calculator make a pipe
I have a guy at work doing up a .cad file for the patterns to mark and cut for roll/weld your own pipes base on stock bore + 15mm2 removed in material removed in exhaust porting the stock port size is 225mm2 so I went 240mm2 thats about 2mill by7 mill removed
so I hope to have at least a pdf for a untested pipe to offer up soon! this is a sore spot for me as spree pipes seam to be on the minds of owners, And with bore and gear kits there to provide more breathing in and out of a engine that was restricted to start with. I would like to see a pipe for the 44 -47 mm kits as people who spend to upgrade will spend to up grade !!
Ill let you know how the new tire roll. 2 mph faster is great when you needed new skins anyway
thanks to all who gave me hope and good advice!! this groups is the bomb ..i've looked at some honda express forums and found no where near this much great help
I much to learn
thanks
