WIX-ONE Posted Thursday at 12:13 PM Report Share Posted Thursday at 12:13 PM Hi All, Total newbie here but i've just bought the Epure race (2 actually, one for the boy). Theres a sound that sounds like a grinding bearing when you add power could this be the drive bearing? I only came to this conclusion after seeing what parts were available and if so is it an easy swap as i cant find any real info out there on the motor and would much rather do it myself. Hope this makes sense! Quote Link to comment Share on other sites More sharing options...
konrad Posted Thursday at 03:06 PM Report Share Posted Thursday at 03:06 PM Have you seen this video on setting the gear gap? https://youtu.be/z8p1JbhZaMw I imagine that could make noise. No real specification, just not too loose and not too tight. Since you have two bikes, you can make some comparisons. Also, by removing the flywheel/primary gear assembly, you can run the motor by itself to verify that is the source of the noise.

WIX-ONE Posted Thursday at 03:24 PM Author Report Share Posted Thursday at 03:24 PM Thanks mate i was hoping you'd reply as i was just looking around your website. I'm going to take the cover off later and have a look to see if its obvious what the noise is so i'll take a video if i'm struggling. I only noticed after riding the other bike (ones been ridden hard the other not so much) but initially thought it was a wheel bearing till i followed the noise and it is coming from behind the flywheel cover.

ChrisCH Posted Thursday at 04:08 PM Report Share Posted Thursday at 04:08 PM I am sure you are a better mechanic than me but one thing to look at with these bikes is chain/transmission noise from rear wheel allignment. I fitted a new chain as the transmission was noisy and the thing got worse. It turns out the snail cams are not the same either side and I had not set the back wheel up properly. Took me quite a while to figure it out but once sorted it was great. Enjoy the bikes, we really enjoy ours but the missus is giving me ear ache for a factor-e so might have to relent as it is xmas...

WIX-ONE Posted Thursday at 04:37 PM Author Report Share Posted Thursday at 04:37 PM Haha i highly doubt that mate, i dont mind having a go though. Cheers for that, i'll have a look to double check, would the wheel rotation be off if thats the case or the line of the chain? That Factor-E is a beast but going off me stacking it first ride out it'd be wasted on me lol. I'm having to hide these bikes till Xmas from the lad, he just thinks the helmet he tried on is for days out at inch perfect. Quote Link to comment Share on other sites More sharing options...
ChrisCH Posted Friday at 09:16 AM Report Share Posted Friday at 09:16 AM Yeah - the chain line was the source of the noise. I bought a new chain (very cheap on ebay) and the noise increased - my bad. Its great now and the bike is 100% Inch perfect have a nice factor-e with a grand off so I have given in to the OH pressure.... We are there 27th to pick up and have a ride. Really hope your lad enjoys it - what a great xmas pressie (cheaper than the wife's 😁) I am sure you will both be OK with the epure - they take a little while to get used to but are a really good ride.

WIX-ONE Posted Friday at 02:39 PM Author Report Share Posted Friday at 02:39 PM Ok managed to get a video. I did start to take the flywheel cover off but blue liquid started to come out so fastened it back up quickly (clutch wont engage now though ffs😂) Quote Link to comment Share on other sites More sharing options...

Cheers mate, he loved it on our experience day so he'll be buzzing. If i cant solve this issue i'll book the bike in there and go for a ride while they fix it 1 Quote Link to comment Share on other sites More sharing options...
