Ah, Jake! Great guy. -----Original Message----- From: Dooden Sent: Sunday, October 16, 2011 7:34 PM To: DSN_KLR650@yahoogroups.com Subject: [DSN_KLR650] Re: Sub frame bolt upgrade. Long Long ago Jake (RIP) sent me a care package that included upgraded bolts and some other cool stuff. Anyhow as he suggested and I totally agree with make sure the subframe bolts are TIGHT and have RED loc-tight. Been that way on my 01 since, and the bolts are the last thing I worry about when riding. If thats Mike's upgrade I seen once, with a drill through and such, agree its better, but I just do not see the need. Just Saying... yes mine has caught air enough to fully bottom out front and back (great take-off/horrible landing) Dooden A15 Green Ape --- In DSN_KLR650@yahoogroups.com, David Nichols wrote:
