Im asking this question for a friend so, its a 94 Honda elite 80, when he tightens the nut on the clutch bell, the back tire will not spin freely. But if you loosen the nut, it will spin freely. I went and took a look at it, and I didnt know what to say. When my clutch nut is tight, my back tire spins freely, maybe the Hondas are different or something, idk. Would anybody know whats going on with it? It has new belt, new rollers, clutch and bell looked fine to me. Back tire will not spin when we tighten the bell/clutch nut. Thanks to all for whatever help is provided!

Anyways, my Mechanic, that use to be the local scooter guy in our town (til he moved) will be coming back to visit, he will be performing the stroker install on my scooter. I've been asking him which to go with, and we both decided to go the 4mm stroker route. He has done plenty of strokers, bbk's, and extensive motor work on cars and trucks, and pretty much anything mechanical. He told me qoute: "whatever we run into I'll take care of" So, I'm going to do the 4mm and let him have at it! I'm paying him, plus he is a dear friend as well. I just have to make sure that I have the crankshaft, 92 link chain, spacer, 61mm gasket kit,etc. Is the spacer on ScooterElements the only size that I will need? Also, are there anymore parts that I need? I wish Walt had a phone number.....

In my small town, we have like 6 stop lights, the police tell us, count to ten, wait for no cars, then proceed. We run the lights if there isnt any traffic! Lol!

What I don't get is, what good is there being a 4mm stroker crankshaft if we cant use it? I would like to get the extra 6 cc's if possible? I dont mind paying more for the 4mm crank over the 3mm. I understand getting the spacer, gaskets for both sides are included (pictures on ScooterElements show gaskets with the spacer) 61mm full gasket set. If the stock  link chain won't work with a 4mm crankshaft, couldn't the 92 link chainwork? If there is slack using a 92 link chain, couldnt there be an adjustent somehow? Walt listed a 61mm kit with the 3mm stroker crank, in the list it said Kymco 94 chain? Why would that 3mm crankshaft need a 94 link chain? I dont mind some extra stuff/work, for a 4mm stroker, I just dont wanna have to shave no piston and stuff. Getting the spacer, 92 link chain,etc. wouldnt that be enough for a 4mm? Sorry guys if I'm being aggravating, I just want the most out of my 61bbk thats all, and going the 4mm direction if at all possible. |

I would probably get all my parts from walt at scooterelements, but I didnt see a spacer for the 61mm bbk. The only one I seen was for 63 I believe...

You need the crank, gasket set the case gaskets break when you split the case and the spacer. Are the case gaskets included with a gasket kit? When I ordered my gasket kit when we did my 61mm rebuild, I'm not sure if the case gaskets were included, it was a NCY 61 gasket kit. |

I got a 92 link chain but I used the stock link chain the 92 link would of been way to long each link is several millimeter. The 92 link will be too big with a 4mm its just one millimeter longer and 1/2 a millimeter in and out stroke. A 4mm needs a least a 2mm spacer. You shim half the stroke the bigger chains are not a direct fit, If I would of added gaskets on each side of the spacer like recommend I would of broke the chain and the longer chain still would of been too big plus I would of loss compression. There's no exact spacer and chain for a bolt on install the 1.57 spacer no gaskets works great with the 3mm. If you do a 4mm you'll have to add gaskets to both sides of the spacer to get the 2mm of clearance plus a little more for heat expansion. You can make the 4mm work but will have chain issues and will have to weld something on the bottom of the tensioner to hold the 92 link chain tight you need to decide if 6cc's more is worth the hassle for me it wasn't. Ok man, That is everything that I needed to hear! Thanks, 3mm it is. Just the spacer, no gaskets, and no chain, correct? |

You'll need to order the crank, gasket set, and spacer I used the spacer with high temp gasket seal on each side the chain was too tight with any gaskets and the spacer. So did you get a chain with the 3mm? If so, which did you get? |

Hey Walt,
I guess you have everything that I'll need for a 4mm stroker?

So I guess a 4mm wouldnt work? Just go with the 3mm? It would but with the spacer the stock chain is sometimes a tight fit. I dont mind ordering the right chain. Which size chain 94 link with a 4mm crank? Doesnt the proper base gasket come with these stroker cranks? I just need a list of every extra part and base gasket needed to do a 4mm stroker. Its funny noone else chimes in with what they have or used? |

Whats the biggest that I can go with, with my 61mm? My mods are in sig below. I dont mind getting 94 link timing chain or base gaskets. Can I go with 4mm or 6mm? If not I will just go with whatever works best..... The max will be 6mm due to the NCY Big Bore kit not having a longer sleeve for the 8.2mm. The 6mm does require modification to the piston. Such as shaving down the piston, making the valve seats deeper and shaving down the bottom of the piston. A machine shop can do that. Otherwise your best bet is a 3mm for the easy install. So I guess a 4mm wouldnt work? Just go with the 3mm? |

Going to be ordering a Stroker crankshaft to complement my NCY 61mm BBK, matching big valve head, A10 cam. Everyone please tell me which crank you have, performance you gained, also which extra parts that were needed for installation. Also How big for my application, and what would be too big. Where did you order from?
Thanks to everyone! Randy

I'm curious did u take the 2000 main spring out ? Because at 6500 to 7000 rpms the 2000 main spring should still alow the clutch pulley to open fully thus your 56 cruising speed will be the same with the stock main spring. Just because your clutch pulley opens sooner doesn't mean u will hit 56 at a lower rpm . I use a 2000 main and the only difference it made was on takeoff and in the mid range. I'm running about he same at 6500 rpms about 55 mph and around 65 between 7 and 7500 rpms. The only way it may make a difference is if for some reason the pulley isn't opened fully at those rpms with the 2000 main. Now if the 2000 main is brand new then it will loosen up after a little while but if u have had it in for a while now it should open fully at those rpms. I love the feeling of the 2000 main as I hit a hill it actually feels like a downshift and the power up hills is great. The only bad thing is it will wear your belt down quicker . I only use the Kevlar gates and I go thru two every summer. I tried a cheap Kevlar that was given to me last yr and it just about disintegrated in 300 miles I only found about 10 small pieces in the variator cover. I took the 2000 main spring out, and put in my spare 1500, I didnt notice any difference in take off, I guess the 2000 spring was in there so long and ridden so much it compressed or broke in or something. My speedometer quit working about 1/1-2 months ago when it was really cold, so I guess I'm not really sure what my speeds are. I'm gonna order a new cable from scrappys today, and maybe slider weights or that spring contraption that keeps the main spring from binding..... |
