9C1 Posted June 23, 2020 Share Posted June 23, 2020 At the risk of shame from my mistake, I put this out there to help others avoid my trouble. I noticed my rear tire had no cap on the valve stem the other day, so I got one out of my tool box and put it on. Next day on the highway I noticed the bike wouldn't move when I went to change lanes and realized my back tire was going flat. Once I was able to inspect it, I saw that the valve stem cap was deformed and saw where it was hitting the caliper. The stupid cap was about 2 or 3 millimeters too tall and this interference broke the stem. Just a word of caution to you fellow VFR owners!

Member Contributer interceptor69 Posted June 23, 2020 Member Contributer Share Posted June 23, 2020 I had the same problem several years ago. The top of the cover was hitting the caliper every rotation and the air pressure slowly dropped until I figured it out. I think next time I get tires on gonna ask for angle valve stems.

Member Contributer Grum Posted June 23, 2020 Member Contributer Share Posted June 23, 2020 Yep. Had it once. New rear tire fitted and was not informed they replaced the valve stem, there was nothing wrong with the original anyway! Fitted the wheel, went for a test ride and faintly heard a tick tick sound. Had to drop the wheel off, then back to the tire place for the shorter stem to be fitted, very annoying. So YES a very good Warning, something to be aware of when getting a new rear tire.

Member Contributer JZH Posted June 24, 2020 Member Contributer Share Posted June 24, 2020 Yes, particularly because fitting the wrong valve stem can result in rapid deflation of the tire--not something you want happening on the motorway, Ciao, JZH Link to comment Share on other sites More sharing options...
Member Contributer interceptor69 Posted June 24, 2020 Member Contributer Share Posted June 24, 2020 Speaking of angled valve stems, are there any drawbacks to having those on the back wheel? Link to comment Share on other sites More sharing options...
Member Contributer MaxSwell Posted June 24, 2020 Member Contributer Share Posted June 24, 2020 I've had angled valve stems for a long time. Never an issue and they've held air pressure well. I do use metal caps and high quality valve inserts. Link to comment Share on other sites More sharing options...
Member Contributer interceptor69 Posted June 24, 2020 Member Contributer Share Posted June 24, 2020 Thanks. I use the same caps as well.Sent from my SM-G975U using Tapatalk Link to comment Share on other sites More sharing options...
Member Contributer vfrcapn Posted June 25, 2020 Member Contributer Share Posted June 25, 2020 I'll plug https://www.kurveygirl.com/shop/index.php for angled stems. Plus they have the best stickers with your order. Link to comment Share on other sites More sharing options...
