I've got an 1199s and I cannot think of any way heat could be transfered to that spot...? Only the swing arm contacts that point but how could it possibly heat up that much to melt the hugger. Could it be a chemical burn of some type?
I bought the bike on Saturday and rode it back from Rotherham to Teesside. The lad I bought it from was about 18 stone, similar to me. I asked him if he'd had the suspension set up and he said no it was all stock setting!? On the ride back I filtered through about 6 to 8 mile of stood /slow moving traffic. SHE GOT HOT So theory is incorrect rear end and heat? Is this plorsible? Andy
Fairly common for that to happen to the heat shield aboove the exhaust but that is the first ive seen on the hugger. Could be as suspension isn't set to your weight, there is too much compression pushing the exhaust too close to the hugger hence the bubbling.
Is that an Oem hugger with a sticker or cheapo eBay aftermarket one?. Had heatshields replaced on my previous 899 twice due to excessive heat, but never the hugger. 18 stone ( with or without gear?) , and Saturday’s heat along with filtering ( perhaps using slightly excessive newbie big vtwin revs) & it’s quite likely it was the heat. Your weight ( did you have a pillion? - if the answer is no - ditch the rear pegs, will save weight & look naff) would bring the exhaust fairly close the the top of the hugger. Options. 1. Get rid of the shield & melt everything else including your ballsack. 2. Stiffen rear sus , however may have an adverse effect on handling on our super smooth roads. 3. Loose weight ( you may be 18 stone of lean muscle, therefore no offence intended - but bet you still make a panigale look like a mini moto). 4. If you were carrying a pillion, ditch him/her or whatever the non gender specific word is these days. If you want to avoid the awkward conversation, redline 1st, 2nd & 3rd when they are sat on the back adjusting their visor. 5. Wait for the annual 3 days of summer to finish & buy a new hugger. Hope you get sorted, let us know what the diagnosis was.
