Great video, My rear mount was the same way and previous owner had like 15 washers on a snapped bolt. Thank you for the guidance!
@@LoveNiiko yeah of course thank you for watching
Awesomeness
Shifted into 2nd and broke the same bolt on the 3rd ride. I wish I watched this video before trying it on my own.
@@lancewalker429 did you get it fixed?
Did you upgrade it to a stronger bolt but the same size because I noticed you didn’t drill anything out so I’m assuming you didn’t go with the three eights?
Yeah I upgraded to a stronger bolt grade 8 m8 1.25x120mm you can find it at Lowe’s it’s exactly the same size. I’m actually out test riding it right now and it got rid most of the vibrations too
@@JamesOnWheels so when you try to shake the engine does it have any play in it ?
@@desertwolfarmory nope, with the stock bolts the engine would move when I’m revving it, but with these new ones, the engine does not move, even when your near redline. I just came back from a 50 mile test ride and I can say it feels pretty SOLID
Can you put a link for the bolts and nuts
@@Strictly_lowlows I have the sizes in the description, just go to Lowe’s that’s where I got it
Where did you get the bolts? And also who’s your insurer. Trying to figure out how I would get it insured
I got the bolts at Lowe’s the measurements are in the description. And it’s insured thru progressive
@@JamesOnWheelsthanks! How much do u have to pay?
@@Titoo2xx about 150 for the whole year
The mount u bolted next to the sprocket, how close does it get to the sprocket? I’m afraid my 17t will hit it if I were to install it the same way u did
It doesn’t hit at all. Ever since I replaced it I have put 1000 miles on the bikes and the bolt has not broken off or caused any issues touching the sprocket
@@JamesOnWheels did u end up putting the sprocket cover back on? Hella ppl tell me that the chain hits the cover and to grind off an inch or so for the chain to clear so I’ve kept it off since the install. Appreciate u bro.
@@slapslap9715 that’s exactly what I did I grind off the plate I think that’s in my sprocket video
I grinded off my sprocket cover and also since then you should go with a 16 teeth more torque and you still have top end
I was curious how is that holding up to today
I've broke the stock lower bolt, and replaced it, later upgrading(drilling out) to a larger bolt. Have had any problems torquing to 40?
Nope i looked up what the grom specifications were and it’s between 35-40 but I haven’t had an issue, 1500 miles later and it’s still holding on Pretty good
@@JamesOnWheels I actually broke a replacement 3/8'th grade 8 bolt. Trying to figure if fluke or I messed up torquing it. Thanks for reply.
Are both top and bottom bolts the same length?
Yeah it’s the same size they’re both class 8 M8 1.25x 120mm bolts
@JamesOnWheels thank you yeah i had my bottom one sheer out yesterday as i was riding from the bolt end going to change today
@@unpredictableiii good luck on the change, lemme know how it goes
So red fox powersports right??
Yeah red Fox power sports
So i hot all the bolts,nuts, and washers. How many washers did you use?
@@trainingfokeeps1314 two for each bolt
I appreciate you
@ of course man lemme know if you have any other questions
