A custom one-of connecting rod might set your net worth back a bit ILove2, IMHO. However, cost doesn't enter into your plans and ambitions significantly, from your posts.
From what Iíve seen on the CWI web site, a custom rod is about $300. Balancing is $200. Stroking with the stock rod is $300. Labor is $125. Rounding the bottom of the rod for additional clearance is $30. All told less than $1000 to get the job done, with one caveat ... longer rods need a piston with the wrist pin moved too.
I havenít been able to source one. I can buy 4, but not one. And I might have a problem with a 105mm bore too. Last vendor doesnít make them that big.
So, if I want to build a stroker with available pistons it means a shorter stroke, shorter rod, and relocating the crankshaft pivot pin outward. Iím not sure if thatís doable since Iíve not even seen the crank, but Iíll give CWI a call tomorrow and see what they can do and/or suggest.
As for cost not entering in to my plans, I assure you it does, but I bought my KLR with an $8K-$10K budget. I only paid 3K for the 2099 KLR. 2K on shocks. So I have $3K-$5K left. If needed, Iíve got another $2K-$3K I can throw into the pot. Iíll be rebuilding a clients server infrastructure and migrating them in to the next decades software over the holidays.
So itís not an infinite budget. Itís just I only get to have one motorcycle to do all the things I want it to do, unlike others with 2,3, or more motorcycles. Iím just trying to give the KLR the best suspension and engine I possibly can.
What does your calendar for boring/stroking/camming/exhausting/intaking/carburating/porting-and-polishing/dynamic balancing/larger valve installation/etc. look like, Ilove2?
I started buying engine parts yesterday. Ordered the oversize valves from Schnitz Racing. Tried to order the cam shafts and heavy duty valve spring kit from Web Cam Racing Cams, but apparently I need to call them. If they require cores, Iíll move on to Hot Cams instead. I prefer the Web Cams but itís $820 for the parts. If I have to include cores I donít think itís going to be worth it to me.
I canít really buy the rest of the parts until I talk to CWI and resolve the piston issue. Anyone know where I can get a single custom piston manufactured?
Bottom line, Iím taking it apart over Thanksgiving week. Shipping out the head to Race Tech for a 5 angle valve seat and fully ported head using the oversize valves and whichever cams I buy.
If I can source a piston for a longer rod I can build what I want. If not, and CWI says I can do it with a shorter rod Iíll go that route using the 719cc BBK from EM. If not, no stroker and just the 719cc BBK.
Looks like your research is essentially complete, awaiting design decisions.
I sooo much want a longer rod and custom piston, but need some help with the custom piston part. Iím running out of places to call.
So, tomorrow Iím hoping my call with CWI bears fruit. Iíll let you know how that works out.
If you see anything Iím missing, please let me know. If you have any ideas on how to finish this stroker build successfully, again, please let me know.
