any options on stripped front sprocket cover bolt

Recommended Posts

I have a 2007 crf150f and I was changing my front sprocket, in the process the bottom bolt of the  front sprocket cover  the two 6mm bolts the bottom one stripped. I have the bolt out but the threads inside the case are gone. I just want to know your opinion. I think I can just tap a new thread just go up to a 8mm. but do you think a 8mm will be too big and when running a 17/64 drill bit for the tap will I hurt anything making the hole to big? im not worried about going in to deep. just will a 8mm bolt be too big for the case and will I hurt anything around it like making anything leak or anything. if anyone isn't familiar with where im talking I can take a picture I just want options. I will prob have to drill the plastic sprocket cover and the case saver too to fit the 8mm into im not worried about that I just am worried about going into the side of my motor. thanks any opinions are appreciated!

Use a 6mm Heli coil, and a new 6mm bolt

Do NOT use an 8mm bolt!

Can I ask why you think that? A 6mm heli coil you need to drill a 1/4 inch hole. Almost same size as 17/64. So the heli coil will be the same size as a 8am bolt going in there. Heli coil are like 35 bucks for the tool and tap idc I just want the easiest way that's will be good to take in and out

"Think" ? Lol

You want an aspirin tablet repair or a permanent repair?

Ask your self these questions.

Is an $35.00 tool a worthwhile investment?

Do you think that there is any possibility that you will ever use it again?

It's an extremely common size.

Most auto part stores and many others RENT tools. (Napa)

Your bike of course, if Jerry rigged is good for you, go for it.

I've seen too many Helicoils fail. If there's any way, I'd rather drill and tap.

So your saying tap a drill for a 8mm?

I understand what yours saying I just don't know your logic on how a tap is just a bandaid fix? I'm defiantly leaning towards a heli coil I'm not arguing with u on that fact. But for the helicoil your doing the same thing then you would tap for pretty much a 8mm but put the Heil coil in? I heard good things and bad things about them. But I would much rather keep a 6mm in there for sure. I was just thinking a straight tap would be better for less things going on and less stuff to break.

      A few picks of my winter project.

      So I want to fit a Speedo to my stock Honda CRF230F, I know people have fitted the Trail Tech endurance to them but they are a bit pricey so my questions are is there another reliable Speedo or is my best choice to bite the bullet and get the Endurance? My other question is the stock stator for the CRF230F enough to power a Speedo or more specifically a trail tech endurance 2? I fully capable of installing it and splicing the wiring, my question is just can the stock bike support it? Also the Bike does not have a headlight.

      I am in the process of slowly repairing everything on my 230 that had been bought from a farmer and obviously had no love ever in its life. Anyway, as I pull off one thing, fix it, reinstall it and then ride around again, I keep coming back to it not being the most aesthetically pleasing 230 on the planet. I was wondering if anyone has suggestions for sticker kits leave 'em below.
      FYI: I would like to keep it as stock looking as possible maybe even use the sticker kits from the last couple years of motorbike.

      I hate finding awesome deals, but not able to make it happen! 
      I found a complete '05 crf150f that I would love to get for the gf and get running. He wants $400 obo. It's a 7 hour drive though. I would have no problem making the drive normally, but even if he'd take $300-350, it would still cost me about $150 in gas. I can't really justify spending the money at this point in time and that sucks balls! 
      I just had to rant for a moment

      Hey guys, 
      Just  finished my xr and wanted to share some pictures with what I done. I have read a lot of posts on suspension for the xr, so I’ll share my mods.I got a set of dnm hornet forks from my wife on my birthday. With a new front I had to do a conversion on the back-so I went with a Crf150f swing arm that got off eBay. After some machine work in a Bridgeport mill removing 5/8 off each side it fit. I removed extra 1/4 inch to allow for chain alignment so it could be shimmed. The  frame was over drilled to 14mm and had to shorten the bolt by removing the bolt head and re-weld a nut to the stud. The shock is temporary until I figure linkage or direct mount but for now it’s a 11 inch fast ace 1100 lbs with adjustable rebound. Also for ease of service I drilled and taped the swinger and shock pivots with 6mm zerks. The wheels are the stock Crf150f and installed Ebc slotted brake pads. 
      The DNM front forks were a challenge as no bearing combination would work with the 41mm race. I used a set of roller taper stock bearings and shimmed the bearing to the triple stem. Brake caliper had to be modified with a new bracket to use the 240 rotor. Also I have yet to find information to support these forks so if anyone has information on these please let me know.. 
      35inch seat height
      as for the rest of the build the motor has a engines only 120 kit with cam and slotted cam sprocket and mikuni tm24 carb. Shower head and oil pump by Daytona and alto red eagle clutch with bbr springs and a hydraulic clutch. Cdi and coil, new seals. installed a bbr  cradle with engines only aluminum front mounts. Had to remove 2mm off the engine and frame dowels to get these to work together. A new seat cover and foam with a clean up on the plastic. Let me know what you think. Thanks
