Riding for the same Factory Team twice in a career?

Brayton on Factory Honda

Short and Canard once their racing career ended went on to roles at Honda.

Jmart and star? 

Chad Reed. Yamaha and Kawasaki.

Didn’t Dowd double dip on Factory Yamaha for 125s? 

I believe Martin Davalos had two stints with Monster Energy/Pro Circuit Kawasaki.

Loracco Suzuki?

MC Honda twice

Bradshaw Yamaha twice

Alessi KTM twice

Millsaps rode Suzuki in the 125 class then 450's later. 

Larry Ward Suzuki 

Josh Hill rode for Factory Yamaha a couple different times.

Depends on what you consider factory, but Brayton at Gibbs. 2010-2011 and 2013-2014. Team Honda 2012.

Josh Grant JGR

That was factory Suzuki on 125s and Bobby Hewitts Rockstar Suzuki team on 450s.  Two different teams.

Nobody mentions Dungey? 
KTM- Retirement- HONDA-back to Retirement- back to KTM.

Forgot Stew was the only factory Suzuki rider that year. 

Brayton JGR

Windham factory Honda (1999-2000, Outdoors 2010 and 11)

KRoc could be setting a record snd going for a third go.

Yes for twice on factory Yamaha.

Kawasaki was 3 times but all different teams. Degroot in GPs, factory Kawi in the US, and kawis on his TwoTwo team.

Hill started his pro career on factory Yamaha and later rode for the Kranyak/Brooks L&M Yamaha team as Stews teamate.

Yes. 90-92 and 96-97.

Didn't Justin Hill return to PC after a stint at TLD KTM?

Technically AP went back to Star in 2021 after Factory Yamaha in 2019 and 2020.

He rode for Factory Yamaha in 2018 as well.

So did Justin Hill I think

Marty Tripes double dipped with Yamaha and Honda. Jimmy Weinert did the same with Yamaha and Kawasaki.

Yep

After aj taught Marty to full time his feet on the pegs...

Brayton has done it several times..

Factory Honda

JGR

MCR

Could also say 3 times for Yamaha and Suzuki, if you count factory teams in Australia.

Larry ward had 2 stints on factory Suzuki.
